Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717912, here are decompositions:

3 + 8717909 = 8717912
31 + 8717881 = 8717912
43 + 8717869 = 8717912
103 + 8717809 = 8717912
109 + 8717803 = 8717912
139 + 8717773 = 8717912
163 + 8717749 = 8717912
223 + 8717689 = 8717912

Showing the first eight; more decompositions exist.
