Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486356, here are decompositions:

17 + 2147486339 = 2147486356
107 + 2147486249 = 2147486356
227 + 2147486129 = 2147486356
347 + 2147486009 = 2147486356
443 + 2147485913 = 2147486356
467 + 2147485889 = 2147486356
479 + 2147485877 = 2147486356
683 + 2147485673 = 2147486356

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.10.148.

Address: 128.0.10.148
