Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57140, here are decompositions:

43 + 57097 = 57140
67 + 57073 = 57140
103 + 57037 = 57140
151 + 56989 = 57140
157 + 56983 = 57140
199 + 56941 = 57140
211 + 56929 = 57140
229 + 56911 = 57140

Showing the first eight; more decompositions exist.
