Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557172, here are decompositions:

29 + 33557143 = 33557172
41 + 33557131 = 33557172
53 + 33557119 = 33557172
71 + 33557101 = 33557172
109 + 33557063 = 33557172
163 + 33557009 = 33557172
179 + 33556993 = 33557172
211 + 33556961 = 33557172

Showing the first eight; more decompositions exist.
