Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486064, here are decompositions:
- 31 + 31486033 = 31486064
- 193 + 31485871 = 31486064
- 241 + 31485823 = 31486064
- 307 + 31485757 = 31486064
- 523 + 31485541 = 31486064
- 751 + 31485313 = 31486064
- 787 + 31485277 = 31486064
- 997 + 31485067 = 31486064
Showing the first eight; more decompositions exist.
