Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642850, here are decompositions:

11 + 8642839 = 8642850
31 + 8642819 = 8642850
89 + 8642761 = 8642850
103 + 8642747 = 8642850
127 + 8642723 = 8642850
199 + 8642651 = 8642850
269 + 8642581 = 8642850
283 + 8642567 = 8642850

Showing the first eight; more decompositions exist.
