Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571388, here are decompositions:

7 + 33571381 = 33571388
61 + 33571327 = 33571388
139 + 33571249 = 33571388
229 + 33571159 = 33571388
439 + 33570949 = 33571388
577 + 33570811 = 33571388
661 + 33570727 = 33571388
967 + 33570421 = 33571388

Showing the first eight; more decompositions exist.
