Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489218, here are decompositions:

11 + 2147489207 = 2147489218
131 + 2147489087 = 2147489218
311 + 2147488907 = 2147489218
359 + 2147488859 = 2147489218
467 + 2147488751 = 2147489218
491 + 2147488727 = 2147489218
599 + 2147488619 = 2147489218
659 + 2147488559 = 2147489218

Showing the first eight; more decompositions exist.

IPv4 address
