Statement \(1:3\) prime numbers are there \(29, 31, 37\), we cannot say which 2 numbers are being added together. So, not sufficient.

Statement \(2: 2+17= 19\).
But we know 19 is the sum of distinct prime factors. So repetition of 2 or 7 may be happening which we are not aware of. So not sufficient.

Statement 1 & 2 together:
\(31+37= 68= 2\cdot 2\cdot 17\)

Hence the value of x is 68
