Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474750, here are decompositions:
- 3 + 31474747 = 31474750
- 17 + 31474733 = 31474750
- 29 + 31474721 = 31474750
- 59 + 31474691 = 31474750
- 149 + 31474601 = 31474750
- 173 + 31474577 = 31474750
- 179 + 31474571 = 31474750
- 191 + 31474559 = 31474750
Showing the first eight; more decompositions exist.
