Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572018, here are decompositions:

79 + 33571939 = 33572018
199 + 33571819 = 33572018
211 + 33571807 = 33572018
349 + 33571669 = 33572018
379 + 33571639 = 33572018
409 + 33571609 = 33572018
421 + 33571597 = 33572018
631 + 33571387 = 33572018

Showing the first eight; more decompositions exist.
