Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612864, here are decompositions:
- 11 + 31612853 = 31612864
- 131 + 31612733 = 31612864
- 137 + 31612727 = 31612864
- 197 + 31612667 = 31612864
- 281 + 31612583 = 31612864
- 317 + 31612547 = 31612864
- 383 + 31612481 = 31612864
- 557 + 31612307 = 31612864
Showing the first eight; more decompositions exist.
