Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545784, here are decompositions:
- 41 + 31545743 = 31545784
- 47 + 31545737 = 31545784
- 71 + 31545713 = 31545784
- 173 + 31545611 = 31545784
- 383 + 31545401 = 31545784
- 461 + 31545323 = 31545784
- 467 + 31545317 = 31545784
- 563 + 31545221 = 31545784
Showing the first eight; more decompositions exist.
