Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490440, here are decompositions:

79 + 2147490361 = 2147490440
97 + 2147490343 = 2147490440
157 + 2147490283 = 2147490440
211 + 2147490229 = 2147490440
223 + 2147490217 = 2147490440
331 + 2147490109 = 2147490440
379 + 2147490061 = 2147490440
499 + 2147489941 = 2147490440

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.136.

Address: 128.0.26.136
Class: public
IPv4-mapped IPv6: ::ffff:128.0.26.136
