Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486572, here are decompositions:

41 + 2147486531 = 2147486572
59 + 2147486513 = 2147486572
71 + 2147486501 = 2147486572
113 + 2147486459 = 2147486572
149 + 2147486423 = 2147486572
173 + 2147486399 = 2147486572
233 + 2147486339 = 2147486572
251 + 2147486321 = 2147486572

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.11.108.
