Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511246, here are decompositions:
- 79 + 31511167 = 31511246
- 103 + 31511143 = 31511246
- 157 + 31511089 = 31511246
- 313 + 31510933 = 31511246
- 337 + 31510909 = 31511246
- 433 + 31510813 = 31511246
- 457 + 31510789 = 31511246
- 619 + 31510627 = 31511246
Showing the first eight; more decompositions exist.
