Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581916, here are decompositions:

47 + 33581869 = 33581916
59 + 33581857 = 33581916
79 + 33581837 = 33581916
97 + 33581819 = 33581916
103 + 33581813 = 33581916
149 + 33581767 = 33581916
223 + 33581693 = 33581916
229 + 33581687 = 33581916

Showing the first eight; more decompositions exist.
