Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572780, here are decompositions:

37 + 33572743 = 33572780
67 + 33572713 = 33572780
79 + 33572701 = 33572780
97 + 33572683 = 33572780
151 + 33572629 = 33572780
223 + 33572557 = 33572780
277 + 33572503 = 33572780
433 + 33572347 = 33572780

Showing the first eight; more decompositions exist.
