Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535576, here are decompositions:
- 73 + 31535503 = 31535576
- 109 + 31535467 = 31535576
- 157 + 31535419 = 31535576
- 199 + 31535377 = 31535576
- 313 + 31535263 = 31535576
- 349 + 31535227 = 31535576
- 433 + 31535143 = 31535576
- 463 + 31535113 = 31535576
Showing the first eight; more decompositions exist.
