Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545752, here are decompositions:
- 3 + 31545749 = 31545752
- 13 + 31545739 = 31545752
- 283 + 31545469 = 31545752
- 313 + 31545439 = 31545752
- 373 + 31545379 = 31545752
- 379 + 31545373 = 31545752
- 409 + 31545343 = 31545752
- 421 + 31545331 = 31545752
Showing the first eight; more decompositions exist.
