Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484640, here are decompositions:

23 + 2147484617 = 2147484640
29 + 2147484611 = 2147484640
71 + 2147484569 = 2147484640
113 + 2147484527 = 2147484640
149 + 2147484491 = 2147484640
179 + 2147484461 = 2147484640
263 + 2147484377 = 2147484640
401 + 2147484239 = 2147484640

Showing the first eight; more decompositions exist.

IPv4 address
