Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8518, here are decompositions:

5 + 8513 = 8518
17 + 8501 = 8518
71 + 8447 = 8518
89 + 8429 = 8518
131 + 8387 = 8518
149 + 8369 = 8518
227 + 8291 = 8518
281 + 8237 = 8518

Showing the first eight; more decompositions exist.
