Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617518, here are decompositions:

5 + 8617513 = 8617518
71 + 8617447 = 8617518
79 + 8617439 = 8617518
101 + 8617417 = 8617518
127 + 8617391 = 8617518
137 + 8617381 = 8617518
157 + 8617361 = 8617518
191 + 8617327 = 8617518

Showing the first eight; more decompositions exist.
