Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609990, here are decompositions:

19 + 33609971 = 33609990
31 + 33609959 = 33609990
59 + 33609931 = 33609990
83 + 33609907 = 33609990
103 + 33609887 = 33609990
173 + 33609817 = 33609990
229 + 33609761 = 33609990
233 + 33609757 = 33609990

Showing the first eight; more decompositions exist.
