Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492970, here are decompositions:

11 + 2147492959 = 2147492970
31 + 2147492939 = 2147492970
41 + 2147492929 = 2147492970
47 + 2147492923 = 2147492970
127 + 2147492843 = 2147492970
211 + 2147492759 = 2147492970
229 + 2147492741 = 2147492970
269 + 2147492701 = 2147492970

Showing the first eight; more decompositions exist.

IPv4 address
