Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618688, here are decompositions:

17 + 33618671 = 33618688
197 + 33618491 = 33618688
359 + 33618329 = 33618688
479 + 33618209 = 33618688
569 + 33618119 = 33618688
659 + 33618029 = 33618688
881 + 33617807 = 33618688
911 + 33617777 = 33618688

Showing the first eight; more decompositions exist.
