Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509872, here are decompositions:

59 + 33509813 = 33509872
89 + 33509783 = 33509872
131 + 33509741 = 33509872
191 + 33509681 = 33509872
239 + 33509633 = 33509872
269 + 33509603 = 33509872
311 + 33509561 = 33509872
443 + 33509429 = 33509872

Showing the first eight; more decompositions exist.
