Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506730, here are decompositions:

41 + 33506689 = 33506730
67 + 33506663 = 33506730
71 + 33506659 = 33506730
107 + 33506623 = 33506730
113 + 33506617 = 33506730
149 + 33506581 = 33506730
151 + 33506579 = 33506730
157 + 33506573 = 33506730

Showing the first eight; more decompositions exist.
