Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509820, here are decompositions:

7 + 33509813 = 33509820
17 + 33509803 = 33509820
37 + 33509783 = 33509820
79 + 33509741 = 33509820
107 + 33509713 = 33509820
137 + 33509683 = 33509820
139 + 33509681 = 33509820
173 + 33509647 = 33509820

Showing the first eight; more decompositions exist.
