Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488892, here are decompositions:

151 + 2147488741 = 2147488892
313 + 2147488579 = 2147488892
349 + 2147488543 = 2147488892
463 + 2147488429 = 2147488892
613 + 2147488279 = 2147488892
643 + 2147488249 = 2147488892
739 + 2147488153 = 2147488892
883 + 2147488009 = 2147488892

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.124.

Address: 128.0.20.124
