Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489162, here are decompositions:

19 + 2147489143 = 2147489162
73 + 2147489089 = 2147489162
79 + 2147489083 = 2147489162
103 + 2147489059 = 2147489162
139 + 2147489023 = 2147489162
421 + 2147488741 = 2147489162
619 + 2147488543 = 2147489162
733 + 2147488429 = 2147489162

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.138.

Address: 128.0.21.138
