Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621810, here are decompositions:

23 + 33621787 = 33621810
29 + 33621781 = 33621810
59 + 33621751 = 33621810
83 + 33621727 = 33621810
97 + 33621713 = 33621810
137 + 33621673 = 33621810
149 + 33621661 = 33621810
181 + 33621629 = 33621810

Showing the first eight; more decompositions exist.
