Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572728, here are decompositions:

29 + 33572699 = 33572728
41 + 33572687 = 33572728
191 + 33572537 = 33572728
239 + 33572489 = 33572728
281 + 33572447 = 33572728
311 + 33572417 = 33572728
347 + 33572381 = 33572728
389 + 33572339 = 33572728

Showing the first eight; more decompositions exist.
