Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572818, here are decompositions:

5 + 33572813 = 33572818
131 + 33572687 = 33572818
281 + 33572537 = 33572818
401 + 33572417 = 33572818
467 + 33572351 = 33572818
479 + 33572339 = 33572818
509 + 33572309 = 33572818
599 + 33572219 = 33572818

Showing the first eight; more decompositions exist.
