Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508818, here are decompositions:

11 + 33508807 = 33508818
17 + 33508801 = 33508818
37 + 33508781 = 33508818
89 + 33508729 = 33508818
97 + 33508721 = 33508818
157 + 33508661 = 33508818
179 + 33508639 = 33508818
191 + 33508627 = 33508818

Showing the first eight; more decompositions exist.
