Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9650, here are decompositions:

7 + 9643 = 9650
19 + 9631 = 9650
31 + 9619 = 9650
37 + 9613 = 9650
103 + 9547 = 9650
139 + 9511 = 9650
211 + 9439 = 9650
229 + 9421 = 9650

Showing the first eight; more decompositions exist.
