Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84666, here are decompositions:

7 + 84659 = 84666
13 + 84653 = 84666
17 + 84649 = 84666
37 + 84629 = 84666
107 + 84559 = 84666
157 + 84509 = 84666
163 + 84503 = 84666
167 + 84499 = 84666

Showing the first eight; more decompositions exist.
