Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486156, here are decompositions:

139 + 2147486017 = 2147486156
157 + 2147485999 = 2147486156
229 + 2147485927 = 2147486156
313 + 2147485843 = 2147486156
337 + 2147485819 = 2147486156
349 + 2147485807 = 2147486156
397 + 2147485759 = 2147486156
709 + 2147485447 = 2147486156

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.9.204.
