Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553818, here are decompositions:

19 + 33553799 = 33553818
31 + 33553787 = 33553818
47 + 33553771 = 33553818
59 + 33553759 = 33553818
71 + 33553747 = 33553818
79 + 33553739 = 33553818
139 + 33553679 = 33553818
157 + 33553661 = 33553818

Showing the first eight; more decompositions exist.
