Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597314, here are decompositions:
- 31 + 31597283 = 31597314
- 53 + 31597261 = 31597314
- 61 + 31597253 = 31597314
- 71 + 31597243 = 31597314
- 83 + 31597231 = 31597314
- 101 + 31597213 = 31597314
- 137 + 31597177 = 31597314
- 163 + 31597151 = 31597314
Showing the first eight; more decompositions exist.
