Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564882, here are decompositions:
- 3 + 31564879 = 31564882
- 29 + 31564853 = 31564882
- 101 + 31564781 = 31564882
- 113 + 31564769 = 31564882
- 233 + 31564649 = 31564882
- 269 + 31564613 = 31564882
- 443 + 31564439 = 31564882
- 449 + 31564433 = 31564882
Showing the first eight; more decompositions exist.
