Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581964, here are decompositions:

7 + 33581957 = 33581964
37 + 33581927 = 33581964
43 + 33581921 = 33581964
103 + 33581861 = 33581964
107 + 33581857 = 33581964
127 + 33581837 = 33581964
151 + 33581813 = 33581964
173 + 33581791 = 33581964

Showing the first eight; more decompositions exist.
