Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640298, here are decompositions:

11 + 8640287 = 8640298
47 + 8640251 = 8640298
101 + 8640197 = 8640298
137 + 8640161 = 8640298
239 + 8640059 = 8640298
281 + 8640017 = 8640298
311 + 8639987 = 8640298
347 + 8639951 = 8640298

Showing the first eight; more decompositions exist.
