Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487626, here are decompositions:

3 + 2147487623 = 2147487626
19 + 2147487607 = 2147487626
223 + 2147487403 = 2147487626
283 + 2147487343 = 2147487626
367 + 2147487259 = 2147487626
379 + 2147487247 = 2147487626
439 + 2147487187 = 2147487626
457 + 2147487169 = 2147487626

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.15.138.

Address: 128.0.15.138
