Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617398, here are decompositions:

7 + 8617391 = 8617398
17 + 8617381 = 8617398
37 + 8617361 = 8617398
71 + 8617327 = 8617398
79 + 8617319 = 8617398
107 + 8617291 = 8617398
137 + 8617261 = 8617398
191 + 8617207 = 8617398

Showing the first eight; more decompositions exist.
