Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645622, here are decompositions:

5 + 8645617 = 8645622
43 + 8645579 = 8645622
79 + 8645543 = 8645622
131 + 8645491 = 8645622
173 + 8645449 = 8645622
179 + 8645443 = 8645622
191 + 8645431 = 8645622
241 + 8645381 = 8645622

Showing the first eight; more decompositions exist.
