Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572928, here are decompositions:

7 + 33572921 = 33572928
17 + 33572911 = 33572928
31 + 33572897 = 33572928
47 + 33572881 = 33572928
71 + 33572857 = 33572928
79 + 33572849 = 33572928
101 + 33572827 = 33572928
149 + 33572779 = 33572928

Showing the first eight; more decompositions exist.
