Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485746, here are decompositions:

59 + 2147485687 = 2147485746
73 + 2147485673 = 2147485746
97 + 2147485649 = 2147485746
173 + 2147485573 = 2147485746
179 + 2147485567 = 2147485746
199 + 2147485547 = 2147485746
223 + 2147485523 = 2147485746
229 + 2147485517 = 2147485746

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.50.
