Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553918, here are decompositions:

17 + 33553901 = 33553918
131 + 33553787 = 33553918
149 + 33553769 = 33553918
179 + 33553739 = 33553918
191 + 33553727 = 33553918
239 + 33553679 = 33553918
257 + 33553661 = 33553918
269 + 33553649 = 33553918

Showing the first eight; more decompositions exist.
