Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490930, here are decompositions:

7 + 2147490923 = 2147490930
31 + 2147490899 = 2147490930
47 + 2147490883 = 2147490930
59 + 2147490871 = 2147490930
97 + 2147490833 = 2147490930
131 + 2147490799 = 2147490930
157 + 2147490773 = 2147490930
191 + 2147490739 = 2147490930

Showing the first eight; more decompositions exist.

IPv4 address
