Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487988, here are decompositions:

19 + 33487969 = 33487988
229 + 33487759 = 33487988
271 + 33487717 = 33487988
307 + 33487681 = 33487988
337 + 33487651 = 33487988
349 + 33487639 = 33487988
367 + 33487621 = 33487988
397 + 33487591 = 33487988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.252.116.

Address: 1.254.252.116
Class: public
IPv4-mapped IPv6: ::ffff:1.254.252.116

Public, routable address (assignable to a host on the internet).
