Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545552, here are decompositions:
- 53 + 31545499 = 31545552
- 83 + 31545469 = 31545552
- 113 + 31545439 = 31545552
- 151 + 31545401 = 31545552
- 173 + 31545379 = 31545552
- 179 + 31545373 = 31545552
- 223 + 31545329 = 31545552
- 229 + 31545323 = 31545552
Showing the first eight; more decompositions exist.
