Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571620, here are decompositions:

11 + 33571609 = 33571620
13 + 33571607 = 33571620
23 + 33571597 = 33571620
97 + 33571523 = 33571620
113 + 33571507 = 33571620
157 + 33571463 = 33571620
163 + 33571457 = 33571620
167 + 33571453 = 33571620

Showing the first eight; more decompositions exist.
