Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609640, here are decompositions:

47 + 33609593 = 33609640
59 + 33609581 = 33609640
101 + 33609539 = 33609640
107 + 33609533 = 33609640
257 + 33609383 = 33609640
263 + 33609377 = 33609640
347 + 33609293 = 33609640
353 + 33609287 = 33609640

Showing the first eight; more decompositions exist.
