Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487248, here are decompositions:

61 + 2147487187 = 2147487248
79 + 2147487169 = 2147487248
199 + 2147487049 = 2147487248
397 + 2147486851 = 2147487248
421 + 2147486827 = 2147487248
457 + 2147486791 = 2147487248
499 + 2147486749 = 2147487248
541 + 2147486707 = 2147487248

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.16.
