Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651250, here are decompositions:

11 + 8651239 = 8651250
17 + 8651233 = 8651250
19 + 8651231 = 8651250
43 + 8651207 = 8651250
59 + 8651191 = 8651250
61 + 8651189 = 8651250
71 + 8651179 = 8651250
89 + 8651161 = 8651250

Showing the first eight; more decompositions exist.
