Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509868, here are decompositions:

47 + 33509821 = 33509868
127 + 33509741 = 33509868
251 + 33509617 = 33509868
307 + 33509561 = 33509868
367 + 33509501 = 33509868
439 + 33509429 = 33509868
467 + 33509401 = 33509868
479 + 33509389 = 33509868

Showing the first eight; more decompositions exist.
