Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85138, here are decompositions:

5 + 85133 = 85138
17 + 85121 = 85138
29 + 85109 = 85138
47 + 85091 = 85138
89 + 85049 = 85138
101 + 85037 = 85138
191 + 84947 = 85138
269 + 84869 = 85138

Showing the first eight; more decompositions exist.
