Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609690, here are decompositions:

7 + 33609683 = 33609690
19 + 33609671 = 33609690
41 + 33609649 = 33609690
83 + 33609607 = 33609690
97 + 33609593 = 33609690
109 + 33609581 = 33609690
151 + 33609539 = 33609690
157 + 33609533 = 33609690

Showing the first eight; more decompositions exist.
