Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513750, here are decompositions:
- 11 + 31513739 = 31513750
- 29 + 31513721 = 31513750
- 41 + 31513709 = 31513750
- 53 + 31513697 = 31513750
- 83 + 31513667 = 31513750
- 89 + 31513661 = 31513750
- 137 + 31513613 = 31513750
- 347 + 31513403 = 31513750
Showing the first eight; more decompositions exist.
