prime numbers

[drnt]

which prime number can be expressed as sum of two other prime numbers

[tohellandback]

sum of two prime numbers is a prime numbers.
so one of the prime numbers must be 2.
other we will need to check and I don't think there is any limit

2+3=5 prime
2+5=7
2+11=13
2+17=19
2+29=31
2+41=43
2+59=61
..
and I am sure there are a lot more

if a is 2, then a raised to any power will be even
in all other cases, a raised to b will be odd.

Let me put it like this
except 2, all prime numbers are odd. odd raised to any power is always odd.

2 raised to any power(not 0) will always be even
