Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618208, here are decompositions:

17 + 33618191 = 33618208
47 + 33618161 = 33618208
59 + 33618149 = 33618208
89 + 33618119 = 33618208
179 + 33618029 = 33618208
251 + 33617957 = 33618208
389 + 33617819 = 33618208
401 + 33617807 = 33618208

Showing the first eight; more decompositions exist.
