Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474740, here are decompositions:
- 7 + 31474733 = 31474740
- 19 + 31474721 = 31474740
- 47 + 31474693 = 31474740
- 53 + 31474687 = 31474740
- 67 + 31474673 = 31474740
- 71 + 31474669 = 31474740
- 139 + 31474601 = 31474740
- 163 + 31474577 = 31474740
Showing the first eight; more decompositions exist.
