Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490220, here are decompositions:

3 + 2147490217 = 2147490220
59 + 2147490161 = 2147490220
131 + 2147490089 = 2147490220
167 + 2147490053 = 2147490220
251 + 2147489969 = 2147490220
263 + 2147489957 = 2147490220
311 + 2147489909 = 2147490220
347 + 2147489873 = 2147490220

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.172.

Address: 128.0.25.172
Class: public
IPv4-mapped IPv6: ::ffff:128.0.25.172
