Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500866, here are decompositions:

53 + 2147500813 = 2147500866
103 + 2147500763 = 2147500866
239 + 2147500627 = 2147500866
307 + 2147500559 = 2147500866
359 + 2147500507 = 2147500866
367 + 2147500499 = 2147500866
373 + 2147500493 = 2147500866
523 + 2147500343 = 2147500866

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.66.

Address: 128.0.67.66
Class: public
IPv4-mapped IPv6: ::ffff:128.0.67.66
