Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691998, here are decompositions:

19 + 8691979 = 8691998
37 + 8691961 = 8691998
61 + 8691937 = 8691998
97 + 8691901 = 8691998
109 + 8691889 = 8691998
199 + 8691799 = 8691998
331 + 8691667 = 8691998
409 + 8691589 = 8691998

Showing the first eight; more decompositions exist.
