Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489786, here are decompositions:

17 + 33489769 = 33489786
23 + 33489763 = 33489786
47 + 33489739 = 33489786
59 + 33489727 = 33489786
73 + 33489713 = 33489786
79 + 33489707 = 33489786
97 + 33489689 = 33489786
103 + 33489683 = 33489786

Showing the first eight; more decompositions exist.
