Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594772, here are decompositions:
- 3 + 31594769 = 31594772
- 43 + 31594729 = 31594772
- 73 + 31594699 = 31594772
- 163 + 31594609 = 31594772
- 193 + 31594579 = 31594772
- 199 + 31594573 = 31594772
- 271 + 31594501 = 31594772
- 283 + 31594489 = 31594772
Showing the first eight; more decompositions exist.
