Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557250, here are decompositions:

47 + 33557203 = 33557250
53 + 33557197 = 33557250
107 + 33557143 = 33557250
131 + 33557119 = 33557250
149 + 33557101 = 33557250
163 + 33557087 = 33557250
173 + 33557077 = 33557250
193 + 33557057 = 33557250

Showing the first eight; more decompositions exist.
