Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485372, here are decompositions:

3 + 2147485369 = 2147485372
29 + 2147485343 = 2147485372
113 + 2147485259 = 2147485372
191 + 2147485181 = 2147485372
239 + 2147485133 = 2147485372
251 + 2147485121 = 2147485372
293 + 2147485079 = 2147485372
443 + 2147484929 = 2147485372

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.188.
