Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531816, here are decompositions:

23 + 33531793 = 33531816
67 + 33531749 = 33531816
79 + 33531737 = 33531816
137 + 33531679 = 33531816
163 + 33531653 = 33531816
229 + 33531587 = 33531816
239 + 33531577 = 33531816
257 + 33531559 = 33531816

Showing the first eight; more decompositions exist.
