Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621938, here are decompositions:

37 + 33621901 = 33621938
79 + 33621859 = 33621938
151 + 33621787 = 33621938
157 + 33621781 = 33621938
211 + 33621727 = 33621938
277 + 33621661 = 33621938
379 + 33621559 = 33621938
397 + 33621541 = 33621938

Showing the first eight; more decompositions exist.
