Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545046, here are decompositions:
- 23 + 31545023 = 31545046
- 83 + 31544963 = 31545046
- 167 + 31544879 = 31545046
- 227 + 31544819 = 31545046
- 263 + 31544783 = 31545046
- 389 + 31544657 = 31545046
- 503 + 31544543 = 31545046
- 653 + 31544393 = 31545046
Showing the first eight; more decompositions exist.
