Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535736, here are decompositions:
- 19 + 31535717 = 31535736
- 79 + 31535657 = 31535736
- 97 + 31535639 = 31535736
- 103 + 31535633 = 31535736
- 233 + 31535503 = 31535736
- 269 + 31535467 = 31535736
- 307 + 31535429 = 31535736
- 313 + 31535423 = 31535736
Showing the first eight; more decompositions exist.
