Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501530, here are decompositions:

11 + 2147501519 = 2147501530
227 + 2147501303 = 2147501530
257 + 2147501273 = 2147501530
281 + 2147501249 = 2147501530
353 + 2147501177 = 2147501530
401 + 2147501129 = 2147501530
521 + 2147501009 = 2147501530
593 + 2147500937 = 2147501530

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.69.218.

Address: 128.0.69.218
Class: public
IPv4-mapped IPv6: ::ffff:128.0.69.218
