Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596686, here are decompositions:
- 7 + 31596679 = 31596686
- 13 + 31596673 = 31596686
- 73 + 31596613 = 31596686
- 103 + 31596583 = 31596686
- 283 + 31596403 = 31596686
- 307 + 31596379 = 31596686
- 379 + 31596307 = 31596686
- 523 + 31596163 = 31596686
Showing the first eight; more decompositions exist.
