Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571540, here are decompositions:

17 + 33571523 = 33571540
53 + 33571487 = 33571540
83 + 33571457 = 33571540
89 + 33571451 = 33571540
173 + 33571367 = 33571540
389 + 33571151 = 33571540
419 + 33571121 = 33571540
449 + 33571091 = 33571540

Showing the first eight; more decompositions exist.
