Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572844, here are decompositions:

17 + 33572827 = 33572844
31 + 33572813 = 33572844
101 + 33572743 = 33572844
103 + 33572741 = 33572844
131 + 33572713 = 33572844
157 + 33572687 = 33572844
197 + 33572647 = 33572844
307 + 33572537 = 33572844

Showing the first eight; more decompositions exist.
