Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553900, here are decompositions:

101 + 33553799 = 33553900
113 + 33553787 = 33553900
131 + 33553769 = 33553900
173 + 33553727 = 33553900
239 + 33553661 = 33553900
251 + 33553649 = 33553900
293 + 33553607 = 33553900
353 + 33553547 = 33553900

Showing the first eight; more decompositions exist.
