Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571818, here are decompositions:

11 + 33571807 = 33571818
17 + 33571801 = 33571818
79 + 33571739 = 33571818
97 + 33571721 = 33571818
109 + 33571709 = 33571818
149 + 33571669 = 33571818
179 + 33571639 = 33571818
191 + 33571627 = 33571818

Showing the first eight; more decompositions exist.
