Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665974, here are decompositions:

7 + 8665967 = 8665974
41 + 8665933 = 8665974
43 + 8665931 = 8665974
61 + 8665913 = 8665974
101 + 8665873 = 8665974
157 + 8665817 = 8665974
197 + 8665777 = 8665974
257 + 8665717 = 8665974

Showing the first eight; more decompositions exist.
