Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622858, here are decompositions:

5 + 8622853 = 8622858
11 + 8622847 = 8622858
17 + 8622841 = 8622858
47 + 8622811 = 8622858
137 + 8622721 = 8622858
151 + 8622707 = 8622858
281 + 8622577 = 8622858
337 + 8622521 = 8622858

Showing the first eight; more decompositions exist.
