Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545530, here are decompositions:
- 31 + 31545499 = 31545530
- 43 + 31545487 = 31545530
- 61 + 31545469 = 31545530
- 139 + 31545391 = 31545530
- 151 + 31545379 = 31545530
- 157 + 31545373 = 31545530
- 199 + 31545331 = 31545530
- 349 + 31545181 = 31545530
Showing the first eight; more decompositions exist.
