Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489936, here are decompositions:

19 + 2147489917 = 2147489936
37 + 2147489899 = 2147489936
139 + 2147489797 = 2147489936
223 + 2147489713 = 2147489936
283 + 2147489653 = 2147489936
349 + 2147489587 = 2147489936
433 + 2147489503 = 2147489936
463 + 2147489473 = 2147489936

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.144.

Address: 128.0.24.144
Class: public
IPv4-mapped IPv6: ::ffff:128.0.24.144
