Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609866, here are decompositions:

79 + 33609787 = 33609866
97 + 33609769 = 33609866
109 + 33609757 = 33609866
337 + 33609529 = 33609866
463 + 33609403 = 33609866
547 + 33609319 = 33609866
607 + 33609259 = 33609866
727 + 33609139 = 33609866

Showing the first eight; more decompositions exist.
