Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489808, here are decompositions:

17 + 33489791 = 33489808
71 + 33489737 = 33489808
101 + 33489707 = 33489808
179 + 33489629 = 33489808
197 + 33489611 = 33489808
239 + 33489569 = 33489808
431 + 33489377 = 33489808
467 + 33489341 = 33489808

Showing the first eight; more decompositions exist.
