Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723124, here are decompositions:

17 + 8723107 = 8723124
43 + 8723081 = 8723124
61 + 8723063 = 8723124
71 + 8723053 = 8723124
83 + 8723041 = 8723124
107 + 8723017 = 8723124
131 + 8722993 = 8723124
211 + 8722913 = 8723124

Showing the first eight; more decompositions exist.
