Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497562, here are decompositions:
- 3 + 31497559 = 31497562
- 11 + 31497551 = 31497562
- 71 + 31497491 = 31497562
- 101 + 31497461 = 31497562
- 113 + 31497449 = 31497562
- 263 + 31497299 = 31497562
- 269 + 31497293 = 31497562
- 311 + 31497251 = 31497562
Showing the first eight; more decompositions exist.
