Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474918, here are decompositions:
- 89 + 31474829 = 31474918
- 197 + 31474721 = 31474918
- 227 + 31474691 = 31474918
- 317 + 31474601 = 31474918
- 347 + 31474571 = 31474918
- 359 + 31474559 = 31474918
- 521 + 31474397 = 31474918
- 599 + 31474319 = 31474918
Showing the first eight; more decompositions exist.
