Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640098, here are decompositions:

97 + 8640001 = 8640098
199 + 8639899 = 8640098
349 + 8639749 = 8640098
499 + 8639599 = 8640098
547 + 8639551 = 8640098
751 + 8639347 = 8640098
937 + 8639161 = 8640098
967 + 8639131 = 8640098

Showing the first eight; more decompositions exist.
