Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545736, here are decompositions:
- 23 + 31545713 = 31545736
- 107 + 31545629 = 31545736
- 113 + 31545623 = 31545736
- 137 + 31545599 = 31545736
- 419 + 31545317 = 31545736
- 449 + 31545287 = 31545736
- 503 + 31545233 = 31545736
- 617 + 31545119 = 31545736
Showing the first eight; more decompositions exist.
