Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723100, here are decompositions:

11 + 8723089 = 8723100
19 + 8723081 = 8723100
37 + 8723063 = 8723100
47 + 8723053 = 8723100
53 + 8723047 = 8723100
59 + 8723041 = 8723100
83 + 8723017 = 8723100
101 + 8722999 = 8723100

Showing the first eight; more decompositions exist.
