Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509842, here are decompositions:

29 + 33509813 = 33509842
59 + 33509783 = 33509842
101 + 33509741 = 33509842
239 + 33509603 = 33509842
269 + 33509573 = 33509842
281 + 33509561 = 33509842
449 + 33509393 = 33509842
563 + 33509279 = 33509842

Showing the first eight; more decompositions exist.
