Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617290, here are decompositions:

13 + 8617277 = 8617290
29 + 8617261 = 8617290
37 + 8617253 = 8617290
53 + 8617237 = 8617290
79 + 8617211 = 8617290
83 + 8617207 = 8617290
89 + 8617201 = 8617290
103 + 8617187 = 8617290

Showing the first eight; more decompositions exist.
