Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521866, here are decompositions:

3 + 33521863 = 33521866
5 + 33521861 = 33521866
23 + 33521843 = 33521866
83 + 33521783 = 33521866
107 + 33521759 = 33521866
113 + 33521753 = 33521866
137 + 33521729 = 33521866
173 + 33521693 = 33521866

Showing the first eight; more decompositions exist.
