Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621780, here are decompositions:

19 + 33621761 = 33621780
29 + 33621751 = 33621780
53 + 33621727 = 33621780
67 + 33621713 = 33621780
89 + 33621691 = 33621780
107 + 33621673 = 33621780
131 + 33621649 = 33621780
151 + 33621629 = 33621780

Showing the first eight; more decompositions exist.
