Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659146, here are decompositions:

47 + 8659099 = 8659146
79 + 8659067 = 8659146
103 + 8659043 = 8659146
109 + 8659037 = 8659146
127 + 8659019 = 8659146
137 + 8659009 = 8659146
149 + 8658997 = 8659146
157 + 8658989 = 8659146

Showing the first eight; more decompositions exist.
