Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489490, here are decompositions:

7 + 2147489483 = 2147489490
17 + 2147489473 = 2147489490
53 + 2147489437 = 2147489490
67 + 2147489423 = 2147489490
89 + 2147489401 = 2147489490
191 + 2147489299 = 2147489490
193 + 2147489297 = 2147489490
199 + 2147489291 = 2147489490

Showing the first eight; more decompositions exist.

IPv4 address
