Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646660, here are decompositions:

53 + 8646607 = 8646660
79 + 8646581 = 8646660
89 + 8646571 = 8646660
101 + 8646559 = 8646660
131 + 8646529 = 8646660
149 + 8646511 = 8646660
157 + 8646503 = 8646660
163 + 8646497 = 8646660

Showing the first eight; more decompositions exist.
