Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499948, here are decompositions:

31 + 2147499917 = 2147499948
107 + 2147499841 = 2147499948
241 + 2147499707 = 2147499948
277 + 2147499671 = 2147499948
331 + 2147499617 = 2147499948
401 + 2147499547 = 2147499948
409 + 2147499539 = 2147499948
439 + 2147499509 = 2147499948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.63.172.

Address: 128.0.63.172
Class: public
