Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490002, here are decompositions:

61 + 2147489941 = 2147490002
103 + 2147489899 = 2147490002
181 + 2147489821 = 2147490002
349 + 2147489653 = 2147490002
499 + 2147489503 = 2147490002
601 + 2147489401 = 2147490002
739 + 2147489263 = 2147490002
859 + 2147489143 = 2147490002

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.210.

Address: 128.0.24.210
Class: public
IPv4-mapped IPv6: ::ffff:128.0.24.210
