Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491626, here are decompositions:

17 + 2147491609 = 2147491626
19 + 2147491607 = 2147491626
23 + 2147491603 = 2147491626
29 + 2147491597 = 2147491626
43 + 2147491583 = 2147491626
53 + 2147491573 = 2147491626
67 + 2147491559 = 2147491626
73 + 2147491553 = 2147491626

Showing the first eight; more decompositions exist.

IPv4 address
