Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723910, here are decompositions:

7 + 8723903 = 8723910
11 + 8723899 = 8723910
17 + 8723893 = 8723910
23 + 8723887 = 8723910
31 + 8723879 = 8723910
59 + 8723851 = 8723910
89 + 8723821 = 8723910
103 + 8723807 = 8723910

Showing the first eight; more decompositions exist.
