Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621798, here are decompositions:

19 + 8621779 = 8621798
181 + 8621617 = 8621798
307 + 8621491 = 8621798
331 + 8621467 = 8621798
421 + 8621377 = 8621798
499 + 8621299 = 8621798
709 + 8621089 = 8621798
751 + 8621047 = 8621798

Showing the first eight; more decompositions exist.
