Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545506, here are decompositions:
- 7 + 31545499 = 31545506
- 19 + 31545487 = 31545506
- 37 + 31545469 = 31545506
- 67 + 31545439 = 31545506
- 127 + 31545379 = 31545506
- 163 + 31545343 = 31545506
- 409 + 31545097 = 31545506
- 439 + 31545067 = 31545506
Showing the first eight; more decompositions exist.
