Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542612, here are decompositions:
- 53 + 31542559 = 31542612
- 89 + 31542523 = 31542612
- 103 + 31542509 = 31542612
- 173 + 31542439 = 31542612
- 193 + 31542419 = 31542612
- 239 + 31542373 = 31542612
- 271 + 31542341 = 31542612
- 331 + 31542281 = 31542612
Showing the first eight; more decompositions exist.
