Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547780, here are decompositions:

11 + 33547769 = 33547780
17 + 33547763 = 33547780
41 + 33547739 = 33547780
53 + 33547727 = 33547780
173 + 33547607 = 33547780
191 + 33547589 = 33547780
197 + 33547583 = 33547780
251 + 33547529 = 33547780

Showing the first eight; more decompositions exist.
