Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486840, here are decompositions:

13 + 2147486827 = 2147486840
151 + 2147486689 = 2147486840
199 + 2147486641 = 2147486840
223 + 2147486617 = 2147486840
241 + 2147486599 = 2147486840
283 + 2147486557 = 2147486840
313 + 2147486527 = 2147486840
409 + 2147486431 = 2147486840

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.120.

Address: 128.0.12.120
Class: public
IPv4-mapped IPv6: ::ffff:128.0.12.120
