Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85266, here are decompositions:

7 + 85259 = 85266
19 + 85247 = 85266
23 + 85243 = 85266
29 + 85237 = 85266
37 + 85229 = 85266
43 + 85223 = 85266
53 + 85213 = 85266
67 + 85199 = 85266

Showing the first eight; more decompositions exist.
