Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668298, here are decompositions:

19 + 8668279 = 8668298
31 + 8668267 = 8668298
97 + 8668201 = 8668298
157 + 8668141 = 8668298
241 + 8668057 = 8668298
337 + 8667961 = 8668298
349 + 8667949 = 8668298
367 + 8667931 = 8668298

Showing the first eight; more decompositions exist.
