Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506538, here are decompositions:

17 + 33506521 = 33506538
29 + 33506509 = 33506538
59 + 33506479 = 33506538
61 + 33506477 = 33506538
137 + 33506401 = 33506538
139 + 33506399 = 33506538
151 + 33506387 = 33506538
179 + 33506359 = 33506538

Showing the first eight; more decompositions exist.
