Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635398, here are decompositions:

17 + 8635381 = 8635398
47 + 8635351 = 8635398
137 + 8635261 = 8635398
139 + 8635259 = 8635398
157 + 8635241 = 8635398
179 + 8635219 = 8635398
199 + 8635199 = 8635398
257 + 8635141 = 8635398

Showing the first eight; more decompositions exist.
