Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547990, here are decompositions:

17 + 33547973 = 33547990
101 + 33547889 = 33547990
227 + 33547763 = 33547990
251 + 33547739 = 33547990
263 + 33547727 = 33547990
383 + 33547607 = 33547990
401 + 33547589 = 33547990
461 + 33547529 = 33547990

Showing the first eight; more decompositions exist.
