Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571830, here are decompositions:

7 + 33571823 = 33571830
11 + 33571819 = 33571830
13 + 33571817 = 33571830
23 + 33571807 = 33571830
29 + 33571801 = 33571830
37 + 33571793 = 33571830
107 + 33571723 = 33571830
109 + 33571721 = 33571830

Showing the first eight; more decompositions exist.
