Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581988, here are decompositions:

31 + 33581957 = 33581988
61 + 33581927 = 33581988
67 + 33581921 = 33581988
127 + 33581861 = 33581988
131 + 33581857 = 33581988
151 + 33581837 = 33581988
197 + 33581791 = 33581988
227 + 33581761 = 33581988

Showing the first eight; more decompositions exist.
