Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723136, here are decompositions:

13 + 8723123 = 8723136
29 + 8723107 = 8723136
47 + 8723089 = 8723136
73 + 8723063 = 8723136
83 + 8723053 = 8723136
89 + 8723047 = 8723136
137 + 8722999 = 8723136
167 + 8722969 = 8723136

Showing the first eight; more decompositions exist.
