Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487776, here are decompositions:

3 + 2147487773 = 2147487776
19 + 2147487757 = 2147487776
73 + 2147487703 = 2147487776
127 + 2147487649 = 2147487776
139 + 2147487637 = 2147487776
367 + 2147487409 = 2147487776
373 + 2147487403 = 2147487776
433 + 2147487343 = 2147487776

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.32.
