Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545566, here are decompositions:
- 67 + 31545499 = 31545566
- 79 + 31545487 = 31545566
- 97 + 31545469 = 31545566
- 127 + 31545439 = 31545566
- 193 + 31545373 = 31545566
- 223 + 31545343 = 31545566
- 499 + 31545067 = 31545566
- 643 + 31544923 = 31545566
Showing the first eight; more decompositions exist.
