Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556638, here are decompositions:

41 + 33556597 = 33556638
67 + 33556571 = 33556638
79 + 33556559 = 33556638
107 + 33556531 = 33556638
109 + 33556529 = 33556638
131 + 33556507 = 33556638
139 + 33556499 = 33556638
179 + 33556459 = 33556638

Showing the first eight; more decompositions exist.
