Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476120, here are decompositions:

11 + 2147476109 = 2147476120
47 + 2147476073 = 2147476120
89 + 2147476031 = 2147476120
149 + 2147475971 = 2147476120
191 + 2147475929 = 2147476120
269 + 2147475851 = 2147476120
467 + 2147475653 = 2147476120
479 + 2147475641 = 2147476120

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.226.152.

Address: 127.255.226.152
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.226.152
