Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723088, here are decompositions:

7 + 8723081 = 8723088
41 + 8723047 = 8723088
47 + 8723041 = 8723088
71 + 8723017 = 8723088
89 + 8722999 = 8723088
97 + 8722991 = 8723088
107 + 8722981 = 8723088
139 + 8722949 = 8723088

Showing the first eight; more decompositions exist.
