Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486712, here are decompositions:

5 + 2147486707 = 2147486712
23 + 2147486689 = 2147486712
43 + 2147486669 = 2147486712
71 + 2147486641 = 2147486712
113 + 2147486599 = 2147486712
181 + 2147486531 = 2147486712
199 + 2147486513 = 2147486712
211 + 2147486501 = 2147486712

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.11.248.

Address: 128.0.11.248
