Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492750, here are decompositions:
- 53 + 31492697 = 31492750
- 59 + 31492691 = 31492750
- 83 + 31492667 = 31492750
- 173 + 31492577 = 31492750
- 197 + 31492553 = 31492750
- 257 + 31492493 = 31492750
- 347 + 31492403 = 31492750
- 431 + 31492319 = 31492750
Showing the first eight; more decompositions exist.
