Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491612, here are decompositions:

3 + 2147491609 = 2147491612
5 + 2147491607 = 2147491612
29 + 2147491583 = 2147491612
53 + 2147491559 = 2147491612
59 + 2147491553 = 2147491612
251 + 2147491361 = 2147491612
263 + 2147491349 = 2147491612
269 + 2147491343 = 2147491612

Showing the first eight; more decompositions exist.

IPv4 address
