Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658622, here are decompositions:

3 + 8658619 = 8658622
41 + 8658581 = 8658622
53 + 8658569 = 8658622
191 + 8658431 = 8658622
239 + 8658383 = 8658622
251 + 8658371 = 8658622
293 + 8658329 = 8658622
389 + 8658233 = 8658622

Showing the first eight; more decompositions exist.
