Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474800, here are decompositions:
- 17 + 31474783 = 31474800
- 23 + 31474777 = 31474800
- 37 + 31474763 = 31474800
- 53 + 31474747 = 31474800
- 67 + 31474733 = 31474800
- 79 + 31474721 = 31474800
- 107 + 31474693 = 31474800
- 109 + 31474691 = 31474800
Showing the first eight; more decompositions exist.
