Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490548, here are decompositions:

19 + 2147490529 = 2147490548
61 + 2147490487 = 2147490548
97 + 2147490451 = 2147490548
331 + 2147490217 = 2147490548
439 + 2147490109 = 2147490548
487 + 2147490061 = 2147490548
601 + 2147489947 = 2147490548
607 + 2147489941 = 2147490548

Showing the first eight; more decompositions exist.

IPv4 address
