Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485752, here are decompositions:

79 + 2147485673 = 2147485752
103 + 2147485649 = 2147485752
179 + 2147485573 = 2147485752
193 + 2147485559 = 2147485752
229 + 2147485523 = 2147485752
331 + 2147485421 = 2147485752
383 + 2147485369 = 2147485752
409 + 2147485343 = 2147485752

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.8.56.
