Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723298, here are decompositions:

107 + 8723191 = 8723298
149 + 8723149 = 8723298
191 + 8723107 = 8723298
251 + 8723047 = 8723298
257 + 8723041 = 8723298
281 + 8723017 = 8723298
307 + 8722991 = 8723298
317 + 8722981 = 8723298

Showing the first eight; more decompositions exist.
