Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609730, here are decompositions:

29 + 33609701 = 33609730
47 + 33609683 = 33609730
59 + 33609671 = 33609730
137 + 33609593 = 33609730
149 + 33609581 = 33609730
191 + 33609539 = 33609730
197 + 33609533 = 33609730
251 + 33609479 = 33609730

Showing the first eight; more decompositions exist.
