Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545866, here are decompositions:
- 7 + 31545859 = 31545866
- 103 + 31545763 = 31545866
- 127 + 31545739 = 31545866
- 199 + 31545667 = 31545866
- 367 + 31545499 = 31545866
- 379 + 31545487 = 31545866
- 397 + 31545469 = 31545866
- 487 + 31545379 = 31545866
Showing the first eight; more decompositions exist.
