Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57152, here are decompositions:

3 + 57149 = 57152
13 + 57139 = 57152
79 + 57073 = 57152
163 + 56989 = 57152
211 + 56941 = 57152
223 + 56929 = 57152
229 + 56923 = 57152
241 + 56911 = 57152

Showing the first eight; more decompositions exist.
