Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500786, here are decompositions:

5 + 2147500781 = 2147500786
23 + 2147500763 = 2147500786
89 + 2147500697 = 2147500786
173 + 2147500613 = 2147500786
227 + 2147500559 = 2147500786
293 + 2147500493 = 2147500786
443 + 2147500343 = 2147500786
647 + 2147500139 = 2147500786

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.66.242.

Address: 128.0.66.242
Class: public
