Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476618, here are decompositions:

11 + 2147476607 = 2147476618
101 + 2147476517 = 2147476618
251 + 2147476367 = 2147476618
449 + 2147476169 = 2147476618
479 + 2147476139 = 2147476618
491 + 2147476127 = 2147476618
509 + 2147476109 = 2147476618
587 + 2147476031 = 2147476618

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.228.138.

Address: 127.255.228.138
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.228.138
