Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584842, here are decompositions:

31 + 2147584811 = 2147584842
61 + 2147584781 = 2147584842
149 + 2147584693 = 2147584842
163 + 2147584679 = 2147584842
173 + 2147584669 = 2147584842
181 + 2147584661 = 2147584842
191 + 2147584651 = 2147584842
233 + 2147584609 = 2147584842

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.139.74.
