Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572838, here are decompositions:

11 + 33572827 = 33572838
59 + 33572779 = 33572838
97 + 33572741 = 33572838
137 + 33572701 = 33572838
139 + 33572699 = 33572838
151 + 33572687 = 33572838
191 + 33572647 = 33572838
281 + 33572557 = 33572838

Showing the first eight; more decompositions exist.
