Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476662, here are decompositions:

13 + 2147476649 = 2147476662
43 + 2147476619 = 2147476662
263 + 2147476399 = 2147476662
281 + 2147476381 = 2147476662
479 + 2147476183 = 2147476662
521 + 2147476141 = 2147476662
523 + 2147476139 = 2147476662
631 + 2147476031 = 2147476662

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.228.182.

Address: 127.255.228.182
