Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509898, here are decompositions:

5 + 33509893 = 33509898
7 + 33509891 = 33509898
157 + 33509741 = 33509898
239 + 33509659 = 33509898
251 + 33509647 = 33509898
281 + 33509617 = 33509898
337 + 33509561 = 33509898
397 + 33509501 = 33509898

Showing the first eight; more decompositions exist.
