Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488130, here are decompositions:

19 + 2147488111 = 2147488130
103 + 2147488027 = 2147488130
199 + 2147487931 = 2147488130
223 + 2147487907 = 2147488130
313 + 2147487817 = 2147488130
331 + 2147487799 = 2147488130
349 + 2147487781 = 2147488130
373 + 2147487757 = 2147488130

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.17.130.

Address: 128.0.17.130
Class: public
