Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545952, here are decompositions:
- 29 + 31545923 = 31545952
- 239 + 31545713 = 31545952
- 311 + 31545641 = 31545952
- 353 + 31545599 = 31545952
- 653 + 31545299 = 31545952
- 719 + 31545233 = 31545952
- 761 + 31545191 = 31545952
- 929 + 31545023 = 31545952
Showing the first eight; more decompositions exist.
