Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516780, here are decompositions:

13 + 33516767 = 33516780
19 + 33516761 = 33516780
29 + 33516751 = 33516780
41 + 33516739 = 33516780
113 + 33516667 = 33516780
149 + 33516631 = 33516780
173 + 33516607 = 33516780
197 + 33516583 = 33516780

Showing the first eight; more decompositions exist.
