Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500678, here are decompositions:

17 + 2147500661 = 2147500678
179 + 2147500499 = 2147500678
317 + 2147500361 = 2147500678
419 + 2147500259 = 2147500678
431 + 2147500247 = 2147500678
761 + 2147499917 = 2147500678
971 + 2147499707 = 2147500678
1061 + 2147499617 = 2147500678

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.66.134.

Address: 128.0.66.134
Class: public
IPv4-mapped IPv6: ::ffff:128.0.66.134
