Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484860, here are decompositions:

109 + 2147484751 = 2147484860
127 + 2147484733 = 2147484860
139 + 2147484721 = 2147484860
163 + 2147484697 = 2147484860
181 + 2147484679 = 2147484860
307 + 2147484553 = 2147484860
421 + 2147484439 = 2147484860
523 + 2147484337 = 2147484860

Showing the first eight; more decompositions exist.

IPv4 address
