Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8530, here are decompositions:

3 + 8527 = 8530
17 + 8513 = 8530
29 + 8501 = 8530
83 + 8447 = 8530
101 + 8429 = 8530
107 + 8423 = 8530
167 + 8363 = 8530
233 + 8297 = 8530

Showing the first eight; more decompositions exist.
