Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505680, here are decompositions:

17 + 33505663 = 33505680
59 + 33505621 = 33505680
79 + 33505601 = 33505680
101 + 33505579 = 33505680
107 + 33505573 = 33505680
113 + 33505567 = 33505680
137 + 33505543 = 33505680
181 + 33505499 = 33505680

Showing the first eight; more decompositions exist.
