Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485256, here are decompositions:

3 + 2147485253 = 2147485256
67 + 2147485189 = 2147485256
199 + 2147485057 = 2147485256
307 + 2147484949 = 2147485256
337 + 2147484919 = 2147485256
379 + 2147484877 = 2147485256
523 + 2147484733 = 2147485256
577 + 2147484679 = 2147485256

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.72.
