Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491576, here are decompositions:

3 + 2147491573 = 2147491576
17 + 2147491559 = 2147491576
23 + 2147491553 = 2147491576
29 + 2147491547 = 2147491576
59 + 2147491517 = 2147491576
173 + 2147491403 = 2147491576
227 + 2147491349 = 2147491576
233 + 2147491343 = 2147491576

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.248.

Address: 128.0.30.248
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.248

Public, routable address (assignable to a host on the internet).
