Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85142, here are decompositions:

61 + 85081 = 85142
151 + 84991 = 85142
163 + 84979 = 85142
181 + 84961 = 85142
223 + 84919 = 85142
229 + 84913 = 85142
271 + 84871 = 85142
283 + 84859 = 85142

Showing the first eight; more decompositions exist.
