Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489234, here are decompositions:

31 + 2147489203 = 2147489234
151 + 2147489083 = 2147489234
157 + 2147489077 = 2147489234
211 + 2147489023 = 2147489234
367 + 2147488867 = 2147489234
661 + 2147488573 = 2147489234
691 + 2147488543 = 2147489234
823 + 2147488411 = 2147489234

Showing the first eight; more decompositions exist.

IPv4 address
