Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557142, here are decompositions:

11 + 33557131 = 33557142
23 + 33557119 = 33557142
41 + 33557101 = 33557142
79 + 33557063 = 33557142
131 + 33557011 = 33557142
149 + 33556993 = 33557142
173 + 33556969 = 33557142
181 + 33556961 = 33557142

Showing the first eight; more decompositions exist.
