Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547648, here are decompositions:

41 + 33547607 = 33547648
59 + 33547589 = 33547648
131 + 33547517 = 33547648
191 + 33547457 = 33547648
227 + 33547421 = 33547648
311 + 33547337 = 33547648
479 + 33547169 = 33547648
509 + 33547139 = 33547648

Showing the first eight; more decompositions exist.
