Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487746, here are decompositions:

43 + 2147487703 = 2147487746
97 + 2147487649 = 2147487746
109 + 2147487637 = 2147487746
139 + 2147487607 = 2147487746
337 + 2147487409 = 2147487746
373 + 2147487373 = 2147487746
487 + 2147487259 = 2147487746
499 + 2147487247 = 2147487746

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.2.
