Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606820, here are decompositions:

17 + 33606803 = 33606820
113 + 33606707 = 33606820
131 + 33606689 = 33606820
167 + 33606653 = 33606820
197 + 33606623 = 33606820
239 + 33606581 = 33606820
293 + 33606527 = 33606820
311 + 33606509 = 33606820

Showing the first eight; more decompositions exist.
