Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547728, here are decompositions:

101 + 33547627 = 33547728
139 + 33547589 = 33547728
191 + 33547537 = 33547728
199 + 33547529 = 33547728
211 + 33547517 = 33547728
239 + 33547489 = 33547728
271 + 33547457 = 33547728
281 + 33547447 = 33547728

Showing the first eight; more decompositions exist.
