Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608872, here are decompositions:

23 + 33608849 = 33608872
149 + 33608723 = 33608872
233 + 33608639 = 33608872
293 + 33608579 = 33608872
449 + 33608423 = 33608872
461 + 33608411 = 33608872
503 + 33608369 = 33608872
509 + 33608363 = 33608872

Showing the first eight; more decompositions exist.
