Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566778, here are decompositions:

17 + 33566761 = 33566778
41 + 33566737 = 33566778
59 + 33566719 = 33566778
97 + 33566681 = 33566778
101 + 33566677 = 33566778
109 + 33566669 = 33566778
131 + 33566647 = 33566778
191 + 33566587 = 33566778

Showing the first eight; more decompositions exist.
