Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511162, here are decompositions:
- 19 + 31511143 = 31511162
- 73 + 31511089 = 31511162
- 229 + 31510933 = 31511162
- 271 + 31510891 = 31511162
- 349 + 31510813 = 31511162
- 373 + 31510789 = 31511162
- 409 + 31510753 = 31511162
- 601 + 31510561 = 31511162
Showing the first eight; more decompositions exist.
