Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572666, here are decompositions:

19 + 33572647 = 33572666
37 + 33572629 = 33572666
109 + 33572557 = 33572666
139 + 33572527 = 33572666
163 + 33572503 = 33572666
313 + 33572353 = 33572666
727 + 33571939 = 33572666
733 + 33571933 = 33572666

Showing the first eight; more decompositions exist.
