Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547538, here are decompositions:

151 + 33547387 = 33547538
229 + 33547309 = 33547538
421 + 33547117 = 33547538
457 + 33547081 = 33547538
487 + 33547051 = 33547538
709 + 33546829 = 33547538
757 + 33546781 = 33547538
907 + 33546631 = 33547538

Showing the first eight; more decompositions exist.
