Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539564, here are decompositions:
- 41 + 31539523 = 31539564
- 97 + 31539467 = 31539564
- 151 + 31539413 = 31539564
- 163 + 31539401 = 31539564
- 197 + 31539367 = 31539564
- 211 + 31539353 = 31539564
- 227 + 31539337 = 31539564
- 233 + 31539331 = 31539564
Showing the first eight; more decompositions exist.
