Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542694, here are decompositions:
- 17 + 31542677 = 31542694
- 107 + 31542587 = 31542694
- 257 + 31542437 = 31542694
- 317 + 31542377 = 31542694
- 353 + 31542341 = 31542694
- 461 + 31542233 = 31542694
- 683 + 31542011 = 31542694
- 761 + 31541933 = 31542694
Showing the first eight; more decompositions exist.
