Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521360, here are decompositions:

139 + 33521221 = 33521360
181 + 33521179 = 33521360
277 + 33521083 = 33521360
373 + 33520987 = 33521360
421 + 33520939 = 33521360
547 + 33520813 = 33521360
577 + 33520783 = 33521360
601 + 33520759 = 33521360

Showing the first eight; more decompositions exist.
