Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528144, here are decompositions:

7 + 33528137 = 33528144
53 + 33528091 = 33528144
103 + 33528041 = 33528144
127 + 33528017 = 33528144
131 + 33528013 = 33528144
137 + 33528007 = 33528144
151 + 33527993 = 33528144
163 + 33527981 = 33528144

Showing the first eight; more decompositions exist.
