Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489628, here are decompositions:

5 + 33489623 = 33489628
17 + 33489611 = 33489628
59 + 33489569 = 33489628
197 + 33489431 = 33489628
251 + 33489377 = 33489628
401 + 33489227 = 33489628
449 + 33489179 = 33489628
761 + 33488867 = 33489628

Showing the first eight; more decompositions exist.
