Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492608, here are decompositions:
- 5 + 31492603 = 31492608
- 11 + 31492597 = 31492608
- 31 + 31492577 = 31492608
- 41 + 31492567 = 31492608
- 67 + 31492541 = 31492608
- 71 + 31492537 = 31492608
- 79 + 31492529 = 31492608
- 131 + 31492477 = 31492608
Showing the first eight; more decompositions exist.
