Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723112, here are decompositions:

5 + 8723107 = 8723112
23 + 8723089 = 8723112
31 + 8723081 = 8723112
59 + 8723053 = 8723112
71 + 8723041 = 8723112
113 + 8722999 = 8723112
131 + 8722981 = 8723112
163 + 8722949 = 8723112

Showing the first eight; more decompositions exist.
