Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618840, here are decompositions:

23 + 33618817 = 33618840
61 + 33618779 = 33618840
67 + 33618773 = 33618840
71 + 33618769 = 33618840
83 + 33618757 = 33618840
89 + 33618751 = 33618840
103 + 33618737 = 33618840
197 + 33618643 = 33618840

Showing the first eight; more decompositions exist.
