Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553806, here are decompositions:

7 + 33553799 = 33553806
19 + 33553787 = 33553806
37 + 33553769 = 33553806
47 + 33553759 = 33553806
59 + 33553747 = 33553806
67 + 33553739 = 33553806
79 + 33553727 = 33553806
109 + 33553697 = 33553806

Showing the first eight; more decompositions exist.
