Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723922, here are decompositions:

13 + 8723909 = 8723922
19 + 8723903 = 8723922
23 + 8723899 = 8723922
29 + 8723893 = 8723922
43 + 8723879 = 8723922
71 + 8723851 = 8723922
89 + 8723833 = 8723922
101 + 8723821 = 8723922

Showing the first eight; more decompositions exist.
