Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486948, here are decompositions:

97 + 2147486851 = 2147486948
157 + 2147486791 = 2147486948
199 + 2147486749 = 2147486948
241 + 2147486707 = 2147486948
307 + 2147486641 = 2147486948
331 + 2147486617 = 2147486948
349 + 2147486599 = 2147486948
421 + 2147486527 = 2147486948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.228.

Address: 128.0.12.228
