Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666074, here are decompositions:

5 + 8666069 = 8666074
17 + 8666057 = 8666074
23 + 8666051 = 8666074
47 + 8666027 = 8666074
83 + 8665991 = 8666074
101 + 8665973 = 8666074
107 + 8665967 = 8666074
257 + 8665817 = 8666074

Showing the first eight; more decompositions exist.
