Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490074, here are decompositions:

13 + 2147490061 = 2147490074
127 + 2147489947 = 2147490074
157 + 2147489917 = 2147490074
277 + 2147489797 = 2147490074
421 + 2147489653 = 2147490074
487 + 2147489587 = 2147490074
571 + 2147489503 = 2147490074
601 + 2147489473 = 2147490074

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.26.

Address: 128.0.25.26
Class: public
IPv4-mapped IPv6: ::ffff:128.0.25.26
