Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85160, here are decompositions:

13 + 85147 = 85160
67 + 85093 = 85160
73 + 85087 = 85160
79 + 85081 = 85160
139 + 85021 = 85160
151 + 85009 = 85160
181 + 84979 = 85160
193 + 84967 = 85160

Showing the first eight; more decompositions exist.
