Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487686, here are decompositions:

37 + 2147487649 = 2147487686
79 + 2147487607 = 2147487686
277 + 2147487409 = 2147487686
283 + 2147487403 = 2147487686
313 + 2147487373 = 2147487686
439 + 2147487247 = 2147487686
499 + 2147487187 = 2147487686
829 + 2147486857 = 2147487686

Showing the first eight; more decompositions exist.

IPv4 address
