Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581940, here are decompositions:

13 + 33581927 = 33581940
19 + 33581921 = 33581940
71 + 33581869 = 33581940
79 + 33581861 = 33581940
83 + 33581857 = 33581940
103 + 33581837 = 33581940
127 + 33581813 = 33581940
149 + 33581791 = 33581940

Showing the first eight; more decompositions exist.
