Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612800, here are decompositions:

3 + 33612797 = 33612800
37 + 33612763 = 33612800
73 + 33612727 = 33612800
97 + 33612703 = 33612800
103 + 33612697 = 33612800
127 + 33612673 = 33612800
157 + 33612643 = 33612800
241 + 33612559 = 33612800

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.228.0.

Address: 2.0.228.0
