Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620884, here are decompositions:

11 + 8620873 = 8620884
23 + 8620861 = 8620884
37 + 8620847 = 8620884
43 + 8620841 = 8620884
127 + 8620757 = 8620884
137 + 8620747 = 8620884
157 + 8620727 = 8620884
163 + 8620721 = 8620884

Showing the first eight; more decompositions exist.
