Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489452, here are decompositions:

11 + 2147489441 = 2147489452
29 + 2147489423 = 2147489452
593 + 2147488859 = 2147489452
659 + 2147488793 = 2147489452
701 + 2147488751 = 2147489452
761 + 2147488691 = 2147489452
809 + 2147488643 = 2147489452
839 + 2147488613 = 2147489452

Showing the first eight; more decompositions exist.

IPv4 address
