Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584572, here are decompositions:

19 + 2147584553 = 2147584572
43 + 2147584529 = 2147584572
53 + 2147584519 = 2147584572
71 + 2147584501 = 2147584572
179 + 2147584393 = 2147584572
181 + 2147584391 = 2147584572
229 + 2147584343 = 2147584572
251 + 2147584321 = 2147584572

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.138.60.
