Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474990, here are decompositions:
- 59 + 31474931 = 31474990
- 227 + 31474763 = 31474990
- 257 + 31474733 = 31474990
- 269 + 31474721 = 31474990
- 317 + 31474673 = 31474990
- 389 + 31474601 = 31474990
- 419 + 31474571 = 31474990
- 431 + 31474559 = 31474990
Showing the first eight; more decompositions exist.
