Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653966, here are decompositions:

3 + 8653963 = 8653966
29 + 8653937 = 8653966
89 + 8653877 = 8653966
107 + 8653859 = 8653966
149 + 8653817 = 8653966
197 + 8653769 = 8653966
257 + 8653709 = 8653966
263 + 8653703 = 8653966

Showing the first eight; more decompositions exist.
