Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666122, here are decompositions:

29 + 8666093 = 8666122
53 + 8666069 = 8666122
71 + 8666051 = 8666122
131 + 8665991 = 8666122
149 + 8665973 = 8666122
173 + 8665949 = 8666122
191 + 8665931 = 8666122
233 + 8665889 = 8666122

Showing the first eight; more decompositions exist.
