Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572656, here are decompositions:

167 + 33572489 = 33572656
239 + 33572417 = 33572656
317 + 33572339 = 33572656
347 + 33572309 = 33572656
353 + 33572303 = 33572656
419 + 33572237 = 33572656
647 + 33572009 = 33572656
659 + 33571997 = 33572656

Showing the first eight; more decompositions exist.
