Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581980, here are decompositions:

23 + 33581957 = 33581980
53 + 33581927 = 33581980
59 + 33581921 = 33581980
167 + 33581813 = 33581980
239 + 33581741 = 33581980
293 + 33581687 = 33581980
359 + 33581621 = 33581980
569 + 33581411 = 33581980

Showing the first eight; more decompositions exist.
