Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486454, here are decompositions:

23 + 2147486431 = 2147486454
31 + 2147486423 = 2147486454
41 + 2147486413 = 2147486454
67 + 2147486387 = 2147486454
137 + 2147486317 = 2147486454
251 + 2147486203 = 2147486454
257 + 2147486197 = 2147486454
307 + 2147486147 = 2147486454

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.10.246.

Address: 128.0.10.246
Class: public
IPv4-mapped IPv6: ::ffff:128.0.10.246
