Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85340, here are decompositions:

7 + 85333 = 85340
37 + 85303 = 85340
43 + 85297 = 85340
97 + 85243 = 85340
103 + 85237 = 85340
127 + 85213 = 85340
139 + 85201 = 85340
181 + 85159 = 85340

Showing the first eight; more decompositions exist.
