Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541750, here are decompositions:
- 13 + 31541737 = 31541750
- 43 + 31541707 = 31541750
- 73 + 31541677 = 31541750
- 139 + 31541611 = 31541750
- 181 + 31541569 = 31541750
- 193 + 31541557 = 31541750
- 223 + 31541527 = 31541750
- 241 + 31541509 = 31541750
Showing the first eight; more decompositions exist.
