Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608720, here are decompositions:

3 + 33608717 = 33608720
37 + 33608683 = 33608720
73 + 33608647 = 33608720
109 + 33608611 = 33608720
139 + 33608581 = 33608720
151 + 33608569 = 33608720
157 + 33608563 = 33608720
181 + 33608539 = 33608720

Showing the first eight; more decompositions exist.
