Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547138, here are decompositions:

29 + 33547109 = 33547138
41 + 33547097 = 33547138
197 + 33546941 = 33547138
467 + 33546671 = 33547138
479 + 33546659 = 33547138
509 + 33546629 = 33547138
587 + 33546551 = 33547138
641 + 33546497 = 33547138

Showing the first eight; more decompositions exist.
