Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649798, here are decompositions:

5 + 8649793 = 8649798
7 + 8649791 = 8649798
37 + 8649761 = 8649798
41 + 8649757 = 8649798
107 + 8649691 = 8649798
109 + 8649689 = 8649798
127 + 8649671 = 8649798
137 + 8649661 = 8649798

Showing the first eight; more decompositions exist.
