Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490086, here are decompositions:

139 + 2147489947 = 2147490086
373 + 2147489713 = 2147490086
433 + 2147489653 = 2147490086
499 + 2147489587 = 2147490086
613 + 2147489473 = 2147490086
739 + 2147489347 = 2147490086
787 + 2147489299 = 2147490086
823 + 2147489263 = 2147490086

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.38.

Address: 128.0.25.38
Class: public
IPv4-mapped IPv6: ::ffff:128.0.25.38
