Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545572, here are decompositions:
- 73 + 31545499 = 31545572
- 103 + 31545469 = 31545572
- 181 + 31545391 = 31545572
- 193 + 31545379 = 31545572
- 199 + 31545373 = 31545572
- 229 + 31545343 = 31545572
- 241 + 31545331 = 31545572
- 523 + 31545049 = 31545572
Showing the first eight; more decompositions exist.
