Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511788, here are decompositions:

19 + 33511769 = 33511788
31 + 33511757 = 33511788
59 + 33511729 = 33511788
61 + 33511727 = 33511788
71 + 33511717 = 33511788
109 + 33511679 = 33511788
127 + 33511661 = 33511788
179 + 33511609 = 33511788

Showing the first eight; more decompositions exist.
