Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545670, here are decompositions:
- 3 + 31545667 = 31545670
- 29 + 31545641 = 31545670
- 41 + 31545629 = 31545670
- 47 + 31545623 = 31545670
- 59 + 31545611 = 31545670
- 71 + 31545599 = 31545670
- 263 + 31545407 = 31545670
- 269 + 31545401 = 31545670
Showing the first eight; more decompositions exist.
