Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666124, here are decompositions:

31 + 8666093 = 8666124
67 + 8666057 = 8666124
73 + 8666051 = 8666124
97 + 8666027 = 8666124
101 + 8666023 = 8666124
107 + 8666017 = 8666124
151 + 8665973 = 8666124
157 + 8665967 = 8666124

Showing the first eight; more decompositions exist.
