Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542790, here are decompositions:
- 3 + 31542787 = 31542790
- 23 + 31542767 = 31542790
- 113 + 31542677 = 31542790
- 131 + 31542659 = 31542790
- 281 + 31542509 = 31542790
- 311 + 31542479 = 31542790
- 353 + 31542437 = 31542790
- 431 + 31542359 = 31542790
Showing the first eight; more decompositions exist.
