Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545666, here are decompositions:
- 37 + 31545629 = 31545666
- 43 + 31545623 = 31545666
- 59 + 31545607 = 31545666
- 67 + 31545599 = 31545666
- 167 + 31545499 = 31545666
- 179 + 31545487 = 31545666
- 197 + 31545469 = 31545666
- 227 + 31545439 = 31545666
Showing the first eight; more decompositions exist.
