Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506772, here are decompositions:

31 + 33506741 = 33506772
83 + 33506689 = 33506772
109 + 33506663 = 33506772
113 + 33506659 = 33506772
149 + 33506623 = 33506772
191 + 33506581 = 33506772
193 + 33506579 = 33506772
199 + 33506573 = 33506772

Showing the first eight; more decompositions exist.
