Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545524, here are decompositions:
- 37 + 31545487 = 31545524
- 151 + 31545373 = 31545524
- 181 + 31545343 = 31545524
- 193 + 31545331 = 31545524
- 313 + 31545211 = 31545524
- 433 + 31545091 = 31545524
- 457 + 31545067 = 31545524
- 463 + 31545061 = 31545524
Showing the first eight; more decompositions exist.
