Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485946, here are decompositions:

7 + 2147485939 = 2147485946
19 + 2147485927 = 2147485946
79 + 2147485867 = 2147485946
103 + 2147485843 = 2147485946
127 + 2147485819 = 2147485946
139 + 2147485807 = 2147485946
373 + 2147485573 = 2147485946
379 + 2147485567 = 2147485946

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.250.
