Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487166, here are decompositions:

3 + 33487163 = 33487166
19 + 33487147 = 33487166
337 + 33486829 = 33487166
367 + 33486799 = 33487166
397 + 33486769 = 33487166
463 + 33486703 = 33487166
619 + 33486547 = 33487166
829 + 33486337 = 33487166

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.249.62.

Address: 1.254.249.62
Class: public
