Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715148, here are decompositions:

5 + 8715143 = 8715148
41 + 8715107 = 8715148
89 + 8715059 = 8715148
107 + 8715041 = 8715148
137 + 8715011 = 8715148
191 + 8714957 = 8715148
227 + 8714921 = 8715148
359 + 8714789 = 8715148

Showing the first eight; more decompositions exist.
