Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572970, here are decompositions:

29 + 33572941 = 33572970
37 + 33572933 = 33572970
43 + 33572927 = 33572970
59 + 33572911 = 33572970
73 + 33572897 = 33572970
89 + 33572881 = 33572970
107 + 33572863 = 33572970
113 + 33572857 = 33572970

Showing the first eight; more decompositions exist.
