Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644698, here are decompositions:

19 + 8644679 = 8644698
37 + 8644661 = 8644698
47 + 8644651 = 8644698
89 + 8644609 = 8644698
191 + 8644507 = 8644698
197 + 8644501 = 8644698
199 + 8644499 = 8644698
241 + 8644457 = 8644698

Showing the first eight; more decompositions exist.
