Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547660, here are decompositions:

53 + 33547607 = 33547660
71 + 33547589 = 33547660
131 + 33547529 = 33547660
227 + 33547433 = 33547660
239 + 33547421 = 33547660
347 + 33547313 = 33547660
383 + 33547277 = 33547660
491 + 33547169 = 33547660

Showing the first eight; more decompositions exist.
