Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509838, here are decompositions:

17 + 33509821 = 33509838
97 + 33509741 = 33509838
157 + 33509681 = 33509838
179 + 33509659 = 33509838
191 + 33509647 = 33509838
269 + 33509569 = 33509838
277 + 33509561 = 33509838
311 + 33509527 = 33509838

Showing the first eight; more decompositions exist.
