Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626398, here are decompositions:

7 + 8626391 = 8626398
97 + 8626301 = 8626398
101 + 8626297 = 8626398
127 + 8626271 = 8626398
149 + 8626249 = 8626398
229 + 8626169 = 8626398
239 + 8626159 = 8626398
257 + 8626141 = 8626398

Showing the first eight; more decompositions exist.
