Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455716, here are decompositions:
- 3 + 31455713 = 31455716
- 13 + 31455703 = 31455716
- 67 + 31455649 = 31455716
- 79 + 31455637 = 31455716
- 283 + 31455433 = 31455716
- 307 + 31455409 = 31455716
- 349 + 31455367 = 31455716
- 577 + 31455139 = 31455716
Showing the first eight; more decompositions exist.
