Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476720, here are decompositions:

71 + 2147476649 = 2147476720
101 + 2147476619 = 2147476720
113 + 2147476607 = 2147476720
353 + 2147476367 = 2147476720
509 + 2147476211 = 2147476720
593 + 2147476127 = 2147476720
647 + 2147476073 = 2147476720
743 + 2147475977 = 2147476720

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.228.240.

Address: 127.255.228.240
