Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621940, here are decompositions:

17 + 33621923 = 33621940
29 + 33621911 = 33621940
59 + 33621881 = 33621940
83 + 33621857 = 33621940
101 + 33621839 = 33621940
179 + 33621761 = 33621940
227 + 33621713 = 33621940
311 + 33621629 = 33621940

Showing the first eight; more decompositions exist.
