Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545446, here are decompositions:
- 7 + 31545439 = 31545446
- 67 + 31545379 = 31545446
- 73 + 31545373 = 31545446
- 103 + 31545343 = 31545446
- 349 + 31545097 = 31545446
- 379 + 31545067 = 31545446
- 397 + 31545049 = 31545446
- 523 + 31544923 = 31545446
Showing the first eight; more decompositions exist.
