Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476372, here are decompositions:

5 + 2147476367 = 2147476372
233 + 2147476139 = 2147476372
263 + 2147476109 = 2147476372
401 + 2147475971 = 2147476372
443 + 2147475929 = 2147476372
521 + 2147475851 = 2147476372
659 + 2147475713 = 2147476372
719 + 2147475653 = 2147476372

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.227.148.

Address: 127.255.227.148
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.227.148
