Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645250, here are decompositions:

7 + 8645243 = 8645250
11 + 8645239 = 8645250
13 + 8645237 = 8645250
71 + 8645179 = 8645250
109 + 8645141 = 8645250
127 + 8645123 = 8645250
137 + 8645113 = 8645250
179 + 8645071 = 8645250

Showing the first eight; more decompositions exist.
