Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584180, here are decompositions:

23 + 2147584157 = 2147584180
167 + 2147584013 = 2147584180
191 + 2147583989 = 2147584180
197 + 2147583983 = 2147584180
233 + 2147583947 = 2147584180
257 + 2147583923 = 2147584180
317 + 2147583863 = 2147584180
347 + 2147583833 = 2147584180

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.136.180.
