Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571842, here are decompositions:

11 + 33571831 = 33571842
13 + 33571829 = 33571842
19 + 33571823 = 33571842
23 + 33571819 = 33571842
41 + 33571801 = 33571842
103 + 33571739 = 33571842
173 + 33571669 = 33571842
179 + 33571663 = 33571842

Showing the first eight; more decompositions exist.
