Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573072, here are decompositions:

19 + 33573053 = 33573072
31 + 33573041 = 33573072
59 + 33573013 = 33573072
89 + 33572983 = 33573072
101 + 33572971 = 33573072
131 + 33572941 = 33573072
139 + 33572933 = 33573072
151 + 33572921 = 33573072

Showing the first eight; more decompositions exist.
