Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465882, here are decompositions:
- 31 + 2147465851 = 2147465882
- 139 + 2147465743 = 2147465882
- 151 + 2147465731 = 2147465882
- 181 + 2147465701 = 2147465882
- 283 + 2147465599 = 2147465882
- 409 + 2147465473 = 2147465882
- 643 + 2147465239 = 2147465882
- 1153 + 2147464729 = 2147465882
Showing the first eight; more decompositions exist.
