Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492860, here are decompositions:

17 + 2147492843 = 2147492860
101 + 2147492759 = 2147492860
239 + 2147492621 = 2147492860
251 + 2147492609 = 2147492860
263 + 2147492597 = 2147492860
269 + 2147492591 = 2147492860
431 + 2147492429 = 2147492860
467 + 2147492393 = 2147492860

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.35.252.

Address: 128.0.35.252
