Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561660, here are decompositions:

7 + 33561653 = 33561660
19 + 33561641 = 33561660
53 + 33561607 = 33561660
61 + 33561599 = 33561660
89 + 33561571 = 33561660
101 + 33561559 = 33561660
103 + 33561557 = 33561660
109 + 33561551 = 33561660

Showing the first eight; more decompositions exist.
