Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491906, here are decompositions:

3 + 2147491903 = 2147491906
149 + 2147491757 = 2147491906
173 + 2147491733 = 2147491906
347 + 2147491559 = 2147491906
353 + 2147491553 = 2147491906
359 + 2147491547 = 2147491906
389 + 2147491517 = 2147491906
503 + 2147491403 = 2147491906

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.32.66.

Address: 128.0.32.66
Class: public
IPv4-mapped IPv6: ::ffff:128.0.32.66
