Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85530, here are decompositions:

7 + 85523 = 85530
13 + 85517 = 85530
17 + 85513 = 85530
43 + 85487 = 85530
61 + 85469 = 85530
79 + 85451 = 85530
83 + 85447 = 85530
101 + 85429 = 85530

Showing the first eight; more decompositions exist.
