Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620660, here are decompositions:

37 + 33620623 = 33620660
43 + 33620617 = 33620660
67 + 33620593 = 33620660
97 + 33620563 = 33620660
181 + 33620479 = 33620660
193 + 33620467 = 33620660
211 + 33620449 = 33620660
223 + 33620437 = 33620660

Showing the first eight; more decompositions exist.
