Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509780, here are decompositions:

37 + 33509743 = 33509780
67 + 33509713 = 33509780
97 + 33509683 = 33509780
163 + 33509617 = 33509780
211 + 33509569 = 33509780
379 + 33509401 = 33509780
457 + 33509323 = 33509780
523 + 33509257 = 33509780

Showing the first eight; more decompositions exist.
