Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8508, here are decompositions:

7 + 8501 = 8508
41 + 8467 = 8508
47 + 8461 = 8508
61 + 8447 = 8508
79 + 8429 = 8508
89 + 8419 = 8508
131 + 8377 = 8508
139 + 8369 = 8508

Showing the first eight; more decompositions exist.
