Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85130, here are decompositions:

37 + 85093 = 85130
43 + 85087 = 85130
103 + 85027 = 85130
109 + 85021 = 85130
139 + 84991 = 85130
151 + 84979 = 85130
163 + 84967 = 85130
211 + 84919 = 85130

Showing the first eight; more decompositions exist.
