Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487712, here are decompositions:

11 + 2147487701 = 2147487712
23 + 2147487689 = 2147487712
89 + 2147487623 = 2147487712
101 + 2147487611 = 2147487712
113 + 2147487599 = 2147487712
239 + 2147487473 = 2147487712
263 + 2147487449 = 2147487712
311 + 2147487401 = 2147487712

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.15.224.

Address: 128.0.15.224
Class: public
IPv4-mapped IPv6: ::ffff:128.0.15.224
