Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516812, here are decompositions:

19 + 33516793 = 33516812
61 + 33516751 = 33516812
73 + 33516739 = 33516812
181 + 33516631 = 33516812
229 + 33516583 = 33516812
283 + 33516529 = 33516812
349 + 33516463 = 33516812
421 + 33516391 = 33516812

Showing the first eight; more decompositions exist.
