Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618172, here are decompositions:

11 + 33618161 = 33618172
23 + 33618149 = 33618172
53 + 33618119 = 33618172
173 + 33617999 = 33618172
239 + 33617933 = 33618172
251 + 33617921 = 33618172
353 + 33617819 = 33618172
443 + 33617729 = 33618172

Showing the first eight; more decompositions exist.
