Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571812, here are decompositions:

5 + 33571807 = 33571812
11 + 33571801 = 33571812
19 + 33571793 = 33571812
73 + 33571739 = 33571812
89 + 33571723 = 33571812
103 + 33571709 = 33571812
149 + 33571663 = 33571812
173 + 33571639 = 33571812

Showing the first eight; more decompositions exist.
