Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643098, here are decompositions:

7 + 8643091 = 8643098
109 + 8642989 = 8643098
151 + 8642947 = 8643098
241 + 8642857 = 8643098
337 + 8642761 = 8643098
631 + 8642467 = 8643098
769 + 8642329 = 8643098
991 + 8642107 = 8643098

Showing the first eight; more decompositions exist.
