Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545558, here are decompositions:
- 59 + 31545499 = 31545558
- 71 + 31545487 = 31545558
- 89 + 31545469 = 31545558
- 151 + 31545407 = 31545558
- 157 + 31545401 = 31545558
- 167 + 31545391 = 31545558
- 179 + 31545379 = 31545558
- 227 + 31545331 = 31545558
Showing the first eight; more decompositions exist.
