Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547642, here are decompositions:

53 + 33547589 = 33547642
59 + 33547583 = 33547642
113 + 33547529 = 33547642
269 + 33547373 = 33547642
389 + 33547253 = 33547642
503 + 33547139 = 33547642
599 + 33547043 = 33547642
701 + 33546941 = 33547642

Showing the first eight; more decompositions exist.
