Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542576, here are decompositions:
- 17 + 31542559 = 31542576
- 29 + 31542547 = 31542576
- 53 + 31542523 = 31542576
- 67 + 31542509 = 31542576
- 89 + 31542487 = 31542576
- 97 + 31542479 = 31542576
- 137 + 31542439 = 31542576
- 139 + 31542437 = 31542576
Showing the first eight; more decompositions exist.
