Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545116, here are decompositions:
- 19 + 31545097 = 31545116
- 67 + 31545049 = 31545116
- 193 + 31544923 = 31545116
- 367 + 31544749 = 31545116
- 397 + 31544719 = 31545116
- 607 + 31544509 = 31545116
- 769 + 31544347 = 31545116
- 937 + 31544179 = 31545116
Showing the first eight; more decompositions exist.
