Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715906, here are decompositions:

5 + 8715901 = 8715906
19 + 8715887 = 8715906
29 + 8715877 = 8715906
113 + 8715793 = 8715906
127 + 8715779 = 8715906
137 + 8715769 = 8715906
197 + 8715709 = 8715906
233 + 8715673 = 8715906

Showing the first eight; more decompositions exist.
