Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547918, here are decompositions:

29 + 33547889 = 33547918
71 + 33547847 = 33547918
149 + 33547769 = 33547918
179 + 33547739 = 33547918
191 + 33547727 = 33547918
311 + 33547607 = 33547918
389 + 33547529 = 33547918
401 + 33547517 = 33547918

Showing the first eight; more decompositions exist.
