Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621816, here are decompositions:

29 + 33621787 = 33621816
89 + 33621727 = 33621816
103 + 33621713 = 33621816
167 + 33621649 = 33621816
223 + 33621593 = 33621816
257 + 33621559 = 33621816
379 + 33621437 = 33621816
409 + 33621407 = 33621816

Showing the first eight; more decompositions exist.
