Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621358, here are decompositions:

19 + 8621339 = 8621358
59 + 8621299 = 8621358
149 + 8621209 = 8621358
157 + 8621201 = 8621358
211 + 8621147 = 8621358
257 + 8621101 = 8621358
269 + 8621089 = 8621358
271 + 8621087 = 8621358

Showing the first eight; more decompositions exist.
