Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457750, here are decompositions:
- 7 + 31457743 = 31457750
- 13 + 31457737 = 31457750
- 31 + 31457719 = 31457750
- 43 + 31457707 = 31457750
- 109 + 31457641 = 31457750
- 139 + 31457611 = 31457750
- 193 + 31457557 = 31457750
- 271 + 31457479 = 31457750
Showing the first eight; more decompositions exist.
