Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8514, here are decompositions:

13 + 8501 = 8514
47 + 8467 = 8514
53 + 8461 = 8514
67 + 8447 = 8514
71 + 8443 = 8514
83 + 8431 = 8514
127 + 8387 = 8514
137 + 8377 = 8514

Showing the first eight; more decompositions exist.
