Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561942, here are decompositions:

13 + 33561929 = 33561942
23 + 33561919 = 33561942
31 + 33561911 = 33561942
61 + 33561881 = 33561942
103 + 33561839 = 33561942
163 + 33561779 = 33561942
173 + 33561769 = 33561942
191 + 33561751 = 33561942

Showing the first eight; more decompositions exist.
