Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620998, here are decompositions:

5 + 8620993 = 8620998
47 + 8620951 = 8620998
101 + 8620897 = 8620998
137 + 8620861 = 8620998
151 + 8620847 = 8620998
157 + 8620841 = 8620998
241 + 8620757 = 8620998
251 + 8620747 = 8620998

Showing the first eight; more decompositions exist.
