Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547472, here are decompositions:

151 + 33547321 = 33547472
163 + 33547309 = 33547472
181 + 33547291 = 33547472
229 + 33547243 = 33547472
379 + 33547093 = 33547472
421 + 33547051 = 33547472
499 + 33546973 = 33547472
601 + 33546871 = 33547472

Showing the first eight; more decompositions exist.
