Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499748, here are decompositions:

41 + 2147499707 = 2147499748
131 + 2147499617 = 2147499748
227 + 2147499521 = 2147499748
239 + 2147499509 = 2147499748
269 + 2147499479 = 2147499748
311 + 2147499437 = 2147499748
347 + 2147499401 = 2147499748
467 + 2147499281 = 2147499748

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.62.228.

Address: 128.0.62.228
Class: public
IPv4-mapped IPv6: ::ffff:128.0.62.228
