Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500188, here are decompositions:

5 + 2147500183 = 2147500188
11 + 2147500177 = 2147500188
61 + 2147500127 = 2147500188
107 + 2147500081 = 2147500188
139 + 2147500049 = 2147500188
181 + 2147500007 = 2147500188
191 + 2147499997 = 2147500188
199 + 2147499989 = 2147500188

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.64.156.

Address: 128.0.64.156
Class: public
IPv4-mapped IPv6: ::ffff:128.0.64.156
