Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596968, here are decompositions:
- 19 + 31596949 = 31596968
- 61 + 31596907 = 31596968
- 79 + 31596889 = 31596968
- 199 + 31596769 = 31596968
- 211 + 31596757 = 31596968
- 307 + 31596661 = 31596968
- 331 + 31596637 = 31596968
- 397 + 31596571 = 31596968
Showing the first eight; more decompositions exist.
