Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491982, here are decompositions:

79 + 2147491903 = 2147491982
151 + 2147491831 = 2147491982
283 + 2147491699 = 2147491982
373 + 2147491609 = 2147491982
379 + 2147491603 = 2147491982
409 + 2147491573 = 2147491982
439 + 2147491543 = 2147491982
613 + 2147491369 = 2147491982

Showing the first eight; more decompositions exist.

IPv4 address
