Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486118, here are decompositions:
- 31 + 31486087 = 31486118
- 109 + 31486009 = 31486118
- 229 + 31485889 = 31486118
- 397 + 31485721 = 31486118
- 457 + 31485661 = 31486118
- 577 + 31485541 = 31486118
- 691 + 31485427 = 31486118
- 739 + 31485379 = 31486118
Showing the first eight; more decompositions exist.
