Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581970, here are decompositions:

13 + 33581957 = 33581970
43 + 33581927 = 33581970
101 + 33581869 = 33581970
109 + 33581861 = 33581970
113 + 33581857 = 33581970
151 + 33581819 = 33581970
157 + 33581813 = 33581970
179 + 33581791 = 33581970

Showing the first eight; more decompositions exist.
