Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509878, here are decompositions:

137 + 33509741 = 33509878
197 + 33509681 = 33509878
317 + 33509561 = 33509878
449 + 33509429 = 33509878
461 + 33509417 = 33509878
587 + 33509291 = 33509878
599 + 33509279 = 33509878
659 + 33509219 = 33509878

Showing the first eight; more decompositions exist.
