Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481894, here are decompositions:

11 + 2147481883 = 2147481894
31 + 2147481863 = 2147481894
67 + 2147481827 = 2147481894
83 + 2147481811 = 2147481894
97 + 2147481797 = 2147481894
101 + 2147481793 = 2147481894
331 + 2147481563 = 2147481894
521 + 2147481373 = 2147481894

Showing the first eight; more decompositions exist.

IPv4 address
