Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723916, here are decompositions:

7 + 8723909 = 8723916
13 + 8723903 = 8723916
17 + 8723899 = 8723916
23 + 8723893 = 8723916
29 + 8723887 = 8723916
37 + 8723879 = 8723916
83 + 8723833 = 8723916
109 + 8723807 = 8723916

Showing the first eight; more decompositions exist.
