Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545708, here are decompositions:
- 41 + 31545667 = 31545708
- 67 + 31545641 = 31545708
- 79 + 31545629 = 31545708
- 97 + 31545611 = 31545708
- 101 + 31545607 = 31545708
- 109 + 31545599 = 31545708
- 239 + 31545469 = 31545708
- 269 + 31545439 = 31545708
Showing the first eight; more decompositions exist.
