Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500870, here are decompositions:

89 + 2147500781 = 2147500870
107 + 2147500763 = 2147500870
173 + 2147500697 = 2147500870
257 + 2147500613 = 2147500870
311 + 2147500559 = 2147500870
509 + 2147500361 = 2147500870
569 + 2147500301 = 2147500870
743 + 2147500127 = 2147500870

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.70.

Address: 128.0.67.70
Class: public
IPv4-mapped IPv6: ::ffff:128.0.67.70
