Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547172, here are decompositions:

3 + 33547169 = 33547172
19 + 33547153 = 33547172
79 + 33547093 = 33547172
151 + 33547021 = 33547172
199 + 33546973 = 33547172
433 + 33546739 = 33547172
541 + 33546631 = 33547172
643 + 33546529 = 33547172

Showing the first eight; more decompositions exist.
