Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489738, here are decompositions:

11 + 33489727 = 33489738
31 + 33489707 = 33489738
89 + 33489649 = 33489738
109 + 33489629 = 33489738
127 + 33489611 = 33489738
179 + 33489559 = 33489738
307 + 33489431 = 33489738
389 + 33489349 = 33489738

Showing the first eight; more decompositions exist.
