Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542610, here are decompositions:
- 23 + 31542587 = 31542610
- 101 + 31542509 = 31542610
- 131 + 31542479 = 31542610
- 173 + 31542437 = 31542610
- 191 + 31542419 = 31542610
- 233 + 31542377 = 31542610
- 251 + 31542359 = 31542610
- 269 + 31542341 = 31542610
Showing the first eight; more decompositions exist.
