Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571788, here are decompositions:

67 + 33571721 = 33571788
79 + 33571709 = 33571788
149 + 33571639 = 33571788
179 + 33571609 = 33571788
181 + 33571607 = 33571788
191 + 33571597 = 33571788
281 + 33571507 = 33571788
331 + 33571457 = 33571788

Showing the first eight; more decompositions exist.
