Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539796, here are decompositions:
- 59 + 31539737 = 31539796
- 83 + 31539713 = 31539796
- 89 + 31539707 = 31539796
- 137 + 31539659 = 31539796
- 227 + 31539569 = 31539796
- 383 + 31539413 = 31539796
- 419 + 31539377 = 31539796
- 443 + 31539353 = 31539796
Showing the first eight; more decompositions exist.
