Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484888, here are decompositions:

11 + 2147484877 = 2147484888
19 + 2147484869 = 2147484888
37 + 2147484851 = 2147484888
67 + 2147484821 = 2147484888
97 + 2147484791 = 2147484888
137 + 2147484751 = 2147484888
167 + 2147484721 = 2147484888
191 + 2147484697 = 2147484888

Showing the first eight; more decompositions exist.

IPv4 address
