Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669158, here are decompositions:

41 + 8669117 = 8669158
131 + 8669027 = 8669158
191 + 8668967 = 8669158
257 + 8668901 = 8669158
269 + 8668889 = 8669158
359 + 8668799 = 8669158
419 + 8668739 = 8669158
461 + 8668697 = 8669158

Showing the first eight; more decompositions exist.
