Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643050, here are decompositions:

37 + 8643013 = 8643050
61 + 8642989 = 8643050
103 + 8642947 = 8643050
139 + 8642911 = 8643050
193 + 8642857 = 8643050
211 + 8642839 = 8643050
277 + 8642773 = 8643050
541 + 8642509 = 8643050

Showing the first eight; more decompositions exist.
