Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566780, here are decompositions:

19 + 33566761 = 33566780
43 + 33566737 = 33566780
61 + 33566719 = 33566780
67 + 33566713 = 33566780
103 + 33566677 = 33566780
193 + 33566587 = 33566780
199 + 33566581 = 33566780
211 + 33566569 = 33566780

Showing the first eight; more decompositions exist.
