Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608820, here are decompositions:

67 + 33608753 = 33608820
83 + 33608737 = 33608820
97 + 33608723 = 33608820
101 + 33608719 = 33608820
103 + 33608717 = 33608820
137 + 33608683 = 33608820
173 + 33608647 = 33608820
181 + 33608639 = 33608820

Showing the first eight; more decompositions exist.
