Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475980, here are decompositions:

17 + 33475963 = 33475980
23 + 33475957 = 33475980
37 + 33475943 = 33475980
61 + 33475919 = 33475980
71 + 33475909 = 33475980
79 + 33475901 = 33475980
113 + 33475867 = 33475980
137 + 33475843 = 33475980

Showing the first eight; more decompositions exist.
