Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565104, here are decompositions:
- 3 + 31565101 = 31565104
- 17 + 31565087 = 31565104
- 47 + 31565057 = 31565104
- 113 + 31564991 = 31565104
- 251 + 31564853 = 31565104
- 383 + 31564721 = 31565104
- 443 + 31564661 = 31565104
- 491 + 31564613 = 31565104
Showing the first eight; more decompositions exist.
