Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571820, here are decompositions:

3 + 33571817 = 33571820
13 + 33571807 = 33571820
19 + 33571801 = 33571820
97 + 33571723 = 33571820
151 + 33571669 = 33571820
157 + 33571663 = 33571820
181 + 33571639 = 33571820
193 + 33571627 = 33571820

Showing the first eight; more decompositions exist.
