Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8538, here are decompositions:

11 + 8527 = 8538
17 + 8521 = 8538
37 + 8501 = 8538
71 + 8467 = 8538
107 + 8431 = 8538
109 + 8429 = 8538
149 + 8389 = 8538
151 + 8387 = 8538

Showing the first eight; more decompositions exist.
