Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723970, here are decompositions:

19 + 8723951 = 8723970
23 + 8723947 = 8723970
37 + 8723933 = 8723970
41 + 8723929 = 8723970
61 + 8723909 = 8723970
67 + 8723903 = 8723970
71 + 8723899 = 8723970
83 + 8723887 = 8723970

Showing the first eight; more decompositions exist.
