Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571928, here are decompositions:

79 + 33571849 = 33571928
97 + 33571831 = 33571928
109 + 33571819 = 33571928
127 + 33571801 = 33571928
331 + 33571597 = 33571928
421 + 33571507 = 33571928
541 + 33571387 = 33571928
547 + 33571381 = 33571928

Showing the first eight; more decompositions exist.
