Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509784, here are decompositions:

41 + 33509743 = 33509784
43 + 33509741 = 33509784
71 + 33509713 = 33509784
101 + 33509683 = 33509784
103 + 33509681 = 33509784
137 + 33509647 = 33509784
151 + 33509633 = 33509784
167 + 33509617 = 33509784

Showing the first eight; more decompositions exist.
