Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509720, here are decompositions:

7 + 33509713 = 33509720
37 + 33509683 = 33509720
61 + 33509659 = 33509720
73 + 33509647 = 33509720
103 + 33509617 = 33509720
151 + 33509569 = 33509720
193 + 33509527 = 33509720
331 + 33509389 = 33509720

Showing the first eight; more decompositions exist.
