Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715154, here are decompositions:

3 + 8715151 = 8715154
11 + 8715143 = 8715154
47 + 8715107 = 8715154
113 + 8715041 = 8715154
131 + 8715023 = 8715154
191 + 8714963 = 8715154
197 + 8714957 = 8715154
233 + 8714921 = 8715154

Showing the first eight; more decompositions exist.
