Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571518, here are decompositions:

11 + 33571507 = 33571518
31 + 33571487 = 33571518
61 + 33571457 = 33571518
67 + 33571451 = 33571518
131 + 33571387 = 33571518
137 + 33571381 = 33571518
151 + 33571367 = 33571518
191 + 33571327 = 33571518

Showing the first eight; more decompositions exist.
