Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490490, here are decompositions:

3 + 2147490487 = 2147490490
227 + 2147490263 = 2147490490
251 + 2147490239 = 2147490490
401 + 2147490089 = 2147490490
479 + 2147490011 = 2147490490
521 + 2147489969 = 2147490490
617 + 2147489873 = 2147490490
641 + 2147489849 = 2147490490

Showing the first eight; more decompositions exist.

IPv4 address
