Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489642, here are decompositions:

3 + 2147489639 = 2147489642
139 + 2147489503 = 2147489642
241 + 2147489401 = 2147489642
379 + 2147489263 = 2147489642
439 + 2147489203 = 2147489642
499 + 2147489143 = 2147489642
619 + 2147489023 = 2147489642
1063 + 2147488579 = 2147489642

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.23.106.

Address: 128.0.23.106
Class: public
IPv4-mapped IPv6: ::ffff:128.0.23.106
