Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545748, here are decompositions:
- 5 + 31545743 = 31545748
- 11 + 31545737 = 31545748
- 107 + 31545641 = 31545748
- 137 + 31545611 = 31545748
- 149 + 31545599 = 31545748
- 347 + 31545401 = 31545748
- 419 + 31545329 = 31545748
- 431 + 31545317 = 31545748
Showing the first eight; more decompositions exist.
