Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670250, here are decompositions:

11 + 8670239 = 8670250
53 + 8670197 = 8670250
59 + 8670191 = 8670250
179 + 8670071 = 8670250
257 + 8669993 = 8670250
269 + 8669981 = 8670250
311 + 8669939 = 8670250
353 + 8669897 = 8670250

Showing the first eight; more decompositions exist.
