Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489974, here are decompositions:

5 + 2147489969 = 2147489974
17 + 2147489957 = 2147489974
101 + 2147489873 = 2147489974
131 + 2147489843 = 2147489974
257 + 2147489717 = 2147489974
431 + 2147489543 = 2147489974
491 + 2147489483 = 2147489974
677 + 2147489297 = 2147489974

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.182.

Address: 128.0.24.182
Class: public
IPv4-mapped IPv6: ::ffff:128.0.24.182
