Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493672, here are decompositions:

11 + 2147493661 = 2147493672
43 + 2147493629 = 2147493672
73 + 2147493599 = 2147493672
83 + 2147493589 = 2147493672
193 + 2147493479 = 2147493672
239 + 2147493433 = 2147493672
263 + 2147493409 = 2147493672
281 + 2147493391 = 2147493672

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.39.40.
