Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492468, here are decompositions:

97 + 2147492371 = 2147492468
139 + 2147492329 = 2147492468
151 + 2147492317 = 2147492468
229 + 2147492239 = 2147492468
307 + 2147492161 = 2147492468
439 + 2147492029 = 2147492468
571 + 2147491897 = 2147492468
631 + 2147491837 = 2147492468

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.34.116.

Address: 128.0.34.116
