Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545776, here are decompositions:
- 13 + 31545763 = 31545776
- 37 + 31545739 = 31545776
- 109 + 31545667 = 31545776
- 277 + 31545499 = 31545776
- 307 + 31545469 = 31545776
- 337 + 31545439 = 31545776
- 397 + 31545379 = 31545776
- 433 + 31545343 = 31545776
Showing the first eight; more decompositions exist.
