Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481818, here are decompositions:

11 + 33481807 = 33481818
17 + 33481801 = 33481818
59 + 33481759 = 33481818
61 + 33481757 = 33481818
67 + 33481751 = 33481818
79 + 33481739 = 33481818
89 + 33481729 = 33481818
191 + 33481627 = 33481818

Showing the first eight; more decompositions exist.
