Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404722, here are decompositions:

11 + 2147404711 = 2147404722
83 + 2147404639 = 2147404722
101 + 2147404621 = 2147404722
103 + 2147404619 = 2147404722
139 + 2147404583 = 2147404722
233 + 2147404489 = 2147404722
283 + 2147404439 = 2147404722
293 + 2147404429 = 2147404722

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.203.178.

Address: 127.254.203.178
