Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571908, here are decompositions:

59 + 33571849 = 33571908
79 + 33571829 = 33571908
89 + 33571819 = 33571908
101 + 33571807 = 33571908
107 + 33571801 = 33571908
199 + 33571709 = 33571908
239 + 33571669 = 33571908
269 + 33571639 = 33571908

Showing the first eight; more decompositions exist.
