Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477068, here are decompositions:
- 5 + 2147477063 = 2147477068
- 47 + 2147477021 = 2147477068
- 89 + 2147476979 = 2147477068
- 131 + 2147476937 = 2147477068
- 137 + 2147476931 = 2147477068
- 197 + 2147476871 = 2147477068
- 227 + 2147476841 = 2147477068
- 419 + 2147476649 = 2147477068
Showing the first eight; more decompositions exist.
