Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665138, here are decompositions:

29 + 8665109 = 8665138
107 + 8665031 = 8665138
179 + 8664959 = 8665138
191 + 8664947 = 8665138
197 + 8664941 = 8665138
269 + 8664869 = 8665138
281 + 8664857 = 8665138
347 + 8664791 = 8665138

Showing the first eight; more decompositions exist.
