Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485258, here are decompositions:

5 + 2147485253 = 2147485258
11 + 2147485247 = 2147485258
137 + 2147485121 = 2147485258
179 + 2147485079 = 2147485258
389 + 2147484869 = 2147485258
467 + 2147484791 = 2147485258
617 + 2147484641 = 2147485258
641 + 2147484617 = 2147485258

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.74.
