Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617284, here are decompositions:

7 + 8617277 = 8617284
23 + 8617261 = 8617284
31 + 8617253 = 8617284
47 + 8617237 = 8617284
73 + 8617211 = 8617284
83 + 8617201 = 8617284
97 + 8617187 = 8617284
107 + 8617177 = 8617284

Showing the first eight; more decompositions exist.
