Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487406, here are decompositions:

3 + 2147487403 = 2147487406
5 + 2147487401 = 2147487406
47 + 2147487359 = 2147487406
137 + 2147487269 = 2147487406
179 + 2147487227 = 2147487406
293 + 2147487113 = 2147487406
347 + 2147487059 = 2147487406
479 + 2147486927 = 2147487406

Showing the first eight; more decompositions exist.

IPv4 address
