Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609780, here are decompositions:

11 + 33609769 = 33609780
19 + 33609761 = 33609780
23 + 33609757 = 33609780
31 + 33609749 = 33609780
37 + 33609743 = 33609780
47 + 33609733 = 33609780
59 + 33609721 = 33609780
79 + 33609701 = 33609780

Showing the first eight; more decompositions exist.
