Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719898, here are decompositions:

67 + 8719831 = 8719898
79 + 8719819 = 8719898
97 + 8719801 = 8719898
127 + 8719771 = 8719898
151 + 8719747 = 8719898
199 + 8719699 = 8719898
307 + 8719591 = 8719898
331 + 8719567 = 8719898

Showing the first eight; more decompositions exist.
