Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489690, here are decompositions:

7 + 33489683 = 33489690
37 + 33489653 = 33489690
41 + 33489649 = 33489690
61 + 33489629 = 33489690
67 + 33489623 = 33489690
71 + 33489619 = 33489690
79 + 33489611 = 33489690
97 + 33489593 = 33489690

Showing the first eight; more decompositions exist.
