Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468872, here are decompositions:

11 + 2147468861 = 2147468872
71 + 2147468801 = 2147468872
89 + 2147468783 = 2147468872
233 + 2147468639 = 2147468872
251 + 2147468621 = 2147468872
281 + 2147468591 = 2147468872
443 + 2147468429 = 2147468872
449 + 2147468423 = 2147468872

Showing the first eight; more decompositions exist.

IPv4 address
