Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485436, here are decompositions:

3 + 2147485433 = 2147485436
13 + 2147485423 = 2147485436
67 + 2147485369 = 2147485436
79 + 2147485357 = 2147485436
127 + 2147485309 = 2147485436
379 + 2147485057 = 2147485436
487 + 2147484949 = 2147485436
739 + 2147484697 = 2147485436

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.252.
