Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33566138, here are decompositions:

31 + 33566107 = 33566138
127 + 33566011 = 33566138
379 + 33565759 = 33566138
409 + 33565729 = 33566138
457 + 33565681 = 33566138
631 + 33565507 = 33566138
769 + 33565369 = 33566138
967 + 33565171 = 33566138

Showing the first eight; more decompositions exist.
