Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488784, here are decompositions:

43 + 2147488741 = 2147488784
211 + 2147488573 = 2147488784
241 + 2147488543 = 2147488784
367 + 2147488417 = 2147488784
373 + 2147488411 = 2147488784
613 + 2147488171 = 2147488784
631 + 2147488153 = 2147488784
673 + 2147488111 = 2147488784

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.16.

Address: 128.0.20.16
Class: public
IPv4-mapped IPv6: ::ffff:128.0.20.16
