Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641252, here are decompositions:

3 + 8641249 = 8641252
5 + 8641247 = 8641252
41 + 8641211 = 8641252
173 + 8641079 = 8641252
491 + 8640761 = 8641252
563 + 8640689 = 8641252
569 + 8640683 = 8641252
1031 + 8640221 = 8641252

Showing the first eight; more decompositions exist.
