Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494494, here are decompositions:

67 + 31494427 = 31494494
193 + 31494301 = 31494494
337 + 31494157 = 31494494
397 + 31494097 = 31494494
613 + 31493881 = 31494494
643 + 31493851 = 31494494
673 + 31493821 = 31494494
751 + 31493743 = 31494494

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.145.94.
