Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584948, here are decompositions:

101 + 2147584847 = 2147584948
137 + 2147584811 = 2147584948
167 + 2147584781 = 2147584948
251 + 2147584697 = 2147584948
269 + 2147584679 = 2147584948
419 + 2147584529 = 2147584948
491 + 2147584457 = 2147584948
557 + 2147584391 = 2147584948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.139.180.
