Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563720, here are decompositions:

31 + 33563689 = 33563720
109 + 33563611 = 33563720
139 + 33563581 = 33563720
283 + 33563437 = 33563720
313 + 33563407 = 33563720
397 + 33563323 = 33563720
439 + 33563281 = 33563720
499 + 33563221 = 33563720

Showing the first eight; more decompositions exist.
