Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715250, here are decompositions:

17 + 8715233 = 8715250
41 + 8715209 = 8715250
59 + 8715191 = 8715250
107 + 8715143 = 8715250
191 + 8715059 = 8715250
227 + 8715023 = 8715250
239 + 8715011 = 8715250
293 + 8714957 = 8715250

Showing the first eight; more decompositions exist.
