Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490636, here are decompositions:

43 + 2147490593 = 2147490636
47 + 2147490589 = 2147490636
59 + 2147490577 = 2147490636
79 + 2147490557 = 2147490636
97 + 2147490539 = 2147490636
107 + 2147490529 = 2147490636
149 + 2147490487 = 2147490636
173 + 2147490463 = 2147490636

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.27.76.
