Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666100, here are decompositions:

7 + 8666093 = 8666100
31 + 8666069 = 8666100
41 + 8666059 = 8666100
43 + 8666057 = 8666100
73 + 8666027 = 8666100
83 + 8666017 = 8666100
101 + 8665999 = 8666100
109 + 8665991 = 8666100

Showing the first eight; more decompositions exist.
