Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618942, here are decompositions:

23 + 33618919 = 33618942
53 + 33618889 = 33618942
89 + 33618853 = 33618942
103 + 33618839 = 33618942
163 + 33618779 = 33618942
173 + 33618769 = 33618942
191 + 33618751 = 33618942
193 + 33618749 = 33618942

Showing the first eight; more decompositions exist.
