Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584668, here are decompositions:

7 + 2147584661 = 2147584668
11 + 2147584657 = 2147584668
17 + 2147584651 = 2147584668
59 + 2147584609 = 2147584668
71 + 2147584597 = 2147584668
139 + 2147584529 = 2147584668
149 + 2147584519 = 2147584668
167 + 2147584501 = 2147584668

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.138.156.

Address: 128.1.138.156
