Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85230, here are decompositions:

7 + 85223 = 85230
17 + 85213 = 85230
29 + 85201 = 85230
31 + 85199 = 85230
37 + 85193 = 85230
71 + 85159 = 85230
83 + 85147 = 85230
97 + 85133 = 85230

Showing the first eight; more decompositions exist.
