Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621660, here are decompositions:

11 + 33621649 = 33621660
31 + 33621629 = 33621660
67 + 33621593 = 33621660
101 + 33621559 = 33621660
223 + 33621437 = 33621660
251 + 33621409 = 33621660
263 + 33621397 = 33621660
271 + 33621389 = 33621660

Showing the first eight; more decompositions exist.
