Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723070, here are decompositions:

7 + 8723063 = 8723070
17 + 8723053 = 8723070
23 + 8723047 = 8723070
29 + 8723041 = 8723070
53 + 8723017 = 8723070
71 + 8722999 = 8723070
79 + 8722991 = 8723070
89 + 8722981 = 8723070

Showing the first eight; more decompositions exist.
