Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568708, here are decompositions:
- 7 + 31568701 = 31568708
- 79 + 31568629 = 31568708
- 97 + 31568611 = 31568708
- 181 + 31568527 = 31568708
- 211 + 31568497 = 31568708
- 397 + 31568311 = 31568708
- 421 + 31568287 = 31568708
- 487 + 31568221 = 31568708
Showing the first eight; more decompositions exist.
