Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611720, here are decompositions:

7 + 33611713 = 33611720
13 + 33611707 = 33611720
19 + 33611701 = 33611720
67 + 33611653 = 33611720
223 + 33611497 = 33611720
271 + 33611449 = 33611720
313 + 33611407 = 33611720
367 + 33611353 = 33611720

Showing the first eight; more decompositions exist.
