Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556042, here are decompositions:

5 + 33556037 = 33556042
53 + 33555989 = 33556042
71 + 33555971 = 33556042
83 + 33555959 = 33556042
383 + 33555659 = 33556042
431 + 33555611 = 33556042
479 + 33555563 = 33556042
593 + 33555449 = 33556042

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.6.74.

Address: 2.0.6.74
Class: public
IPv4-mapped IPv6: ::ffff:2.0.6.74

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