Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486830, here are decompositions:

3 + 2147486827 = 2147486830
11 + 2147486819 = 2147486830
89 + 2147486741 = 2147486830
317 + 2147486513 = 2147486830
431 + 2147486399 = 2147486830
443 + 2147486387 = 2147486830
491 + 2147486339 = 2147486830
509 + 2147486321 = 2147486830

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.12.110.
