Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485374, here are decompositions:

5 + 2147485369 = 2147485374
17 + 2147485357 = 2147485374
31 + 2147485343 = 2147485374
37 + 2147485337 = 2147485374
107 + 2147485267 = 2147485374
113 + 2147485261 = 2147485374
127 + 2147485247 = 2147485374
173 + 2147485201 = 2147485374

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.190.
