Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723154, here are decompositions:

5 + 8723149 = 8723154
17 + 8723137 = 8723154
31 + 8723123 = 8723154
47 + 8723107 = 8723154
73 + 8723081 = 8723154
101 + 8723053 = 8723154
107 + 8723047 = 8723154
113 + 8723041 = 8723154

Showing the first eight; more decompositions exist.
