Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555228, here are decompositions:

11 + 33555217 = 33555228
19 + 33555209 = 33555228
29 + 33555199 = 33555228
37 + 33555191 = 33555228
61 + 33555167 = 33555228
79 + 33555149 = 33555228
97 + 33555131 = 33555228
127 + 33555101 = 33555228

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.3.28.

Address: 2.0.3.28
