Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561338, here are decompositions:

67 + 33561271 = 33561338
157 + 33561181 = 33561338
199 + 33561139 = 33561338
271 + 33561067 = 33561338
331 + 33561007 = 33561338
409 + 33560929 = 33561338
457 + 33560881 = 33561338
487 + 33560851 = 33561338

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.26.250.

Address: 2.0.26.250
Class: public
IPv4-mapped IPv6: ::ffff:2.0.26.250

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