Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492560, here are decompositions:

71 + 2147492489 = 2147492560
113 + 2147492447 = 2147492560
131 + 2147492429 = 2147492560
167 + 2147492393 = 2147492560
173 + 2147492387 = 2147492560
233 + 2147492327 = 2147492560
263 + 2147492297 = 2147492560
401 + 2147492159 = 2147492560

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.34.208.

Address: 128.0.34.208
