Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509988, here are decompositions:

19 + 33509969 = 33509988
59 + 33509929 = 33509988
67 + 33509921 = 33509988
97 + 33509891 = 33509988
167 + 33509821 = 33509988
307 + 33509681 = 33509988
419 + 33509569 = 33509988
461 + 33509527 = 33509988

Showing the first eight; more decompositions exist.
