Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533920, here are decompositions:

47 + 33533873 = 33533920
53 + 33533867 = 33533920
59 + 33533861 = 33533920
83 + 33533837 = 33533920
113 + 33533807 = 33533920
257 + 33533663 = 33533920
467 + 33533453 = 33533920
599 + 33533321 = 33533920

Showing the first eight; more decompositions exist.
