Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668974, here are decompositions:

7 + 8668967 = 8668974
23 + 8668951 = 8668974
73 + 8668901 = 8668974
101 + 8668873 = 8668974
137 + 8668837 = 8668974
157 + 8668817 = 8668974
173 + 8668801 = 8668974
191 + 8668783 = 8668974

Showing the first eight; more decompositions exist.
