Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476988, here are decompositions:

37 + 2147476951 = 2147476988
61 + 2147476927 = 2147476988
199 + 2147476789 = 2147476988
211 + 2147476777 = 2147476988
571 + 2147476417 = 2147476988
607 + 2147476381 = 2147476988
661 + 2147476327 = 2147476988
739 + 2147476249 = 2147476988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.229.252.

Address: 127.255.229.252
