Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547664, here are decompositions:

37 + 33547627 = 33547664
127 + 33547537 = 33547664
151 + 33547513 = 33547664
277 + 33547387 = 33547664
373 + 33547291 = 33547664
421 + 33547243 = 33547664
547 + 33547117 = 33547664
571 + 33547093 = 33547664

Showing the first eight; more decompositions exist.
