Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457854, here are decompositions:
- 5 + 31457849 = 31457854
- 11 + 31457843 = 31457854
- 23 + 31457831 = 31457854
- 83 + 31457771 = 31457854
- 101 + 31457753 = 31457854
- 137 + 31457717 = 31457854
- 167 + 31457687 = 31457854
- 173 + 31457681 = 31457854
Showing the first eight; more decompositions exist.
