Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490380, here are decompositions:

19 + 2147490361 = 2147490380
37 + 2147490343 = 2147490380
97 + 2147490283 = 2147490380
151 + 2147490229 = 2147490380
163 + 2147490217 = 2147490380
271 + 2147490109 = 2147490380
433 + 2147489947 = 2147490380
439 + 2147489941 = 2147490380

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.76.

Address: 128.0.26.76
Class: public
IPv4-mapped IPv6: ::ffff:128.0.26.76
