Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85148, here are decompositions:

61 + 85087 = 85148
67 + 85081 = 85148
127 + 85021 = 85148
139 + 85009 = 85148
157 + 84991 = 85148
181 + 84967 = 85148
229 + 84919 = 85148
277 + 84871 = 85148

Showing the first eight; more decompositions exist.
