Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715486, here are decompositions:

37 + 8715449 = 8715486
83 + 8715403 = 8715486
103 + 8715383 = 8715486
137 + 8715349 = 8715486
139 + 8715347 = 8715486
149 + 8715337 = 8715486
163 + 8715323 = 8715486
223 + 8715263 = 8715486

Showing the first eight; more decompositions exist.
