Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641750, here are decompositions:

3 + 8641747 = 8641750
17 + 8641733 = 8641750
41 + 8641709 = 8641750
53 + 8641697 = 8641750
107 + 8641643 = 8641750
137 + 8641613 = 8641750
179 + 8641571 = 8641750
233 + 8641517 = 8641750

Showing the first eight; more decompositions exist.
