Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478296, here are decompositions:
- 3 + 2147478293 = 2147478296
- 37 + 2147478259 = 2147478296
- 43 + 2147478253 = 2147478296
- 163 + 2147478133 = 2147478296
- 283 + 2147478013 = 2147478296
- 307 + 2147477989 = 2147478296
- 463 + 2147477833 = 2147478296
- 487 + 2147477809 = 2147478296
Showing the first eight; more decompositions exist.
