Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723994, here are decompositions:

7 + 8723987 = 8723994
17 + 8723977 = 8723994
43 + 8723951 = 8723994
47 + 8723947 = 8723994
61 + 8723933 = 8723994
73 + 8723921 = 8723994
101 + 8723893 = 8723994
107 + 8723887 = 8723994

Showing the first eight; more decompositions exist.
