Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490470, here are decompositions:

7 + 2147490463 = 2147490470
19 + 2147490451 = 2147490470
109 + 2147490361 = 2147490470
127 + 2147490343 = 2147490470
241 + 2147490229 = 2147490470
409 + 2147490061 = 2147490470
523 + 2147489947 = 2147490470
571 + 2147489899 = 2147490470

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.166.

Address: 128.0.26.166
Class: public
IPv4-mapped IPv6: ::ffff:128.0.26.166
