Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500798, here are decompositions:

17 + 2147500781 = 2147500798
101 + 2147500697 = 2147500798
137 + 2147500661 = 2147500798
239 + 2147500559 = 2147500798
557 + 2147500241 = 2147500798
659 + 2147500139 = 2147500798
809 + 2147499989 = 2147500798
881 + 2147499917 = 2147500798

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.66.254.

Address: 128.0.66.254
Class: public
