Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505638, here are decompositions:

7 + 33505631 = 33505638
17 + 33505621 = 33505638
37 + 33505601 = 33505638
59 + 33505579 = 33505638
71 + 33505567 = 33505638
139 + 33505499 = 33505638
191 + 33505447 = 33505638
197 + 33505441 = 33505638

Showing the first eight; more decompositions exist.
