Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9628, here are decompositions:

5 + 9623 = 9628
41 + 9587 = 9628
89 + 9539 = 9628
107 + 9521 = 9628
131 + 9497 = 9628
137 + 9491 = 9628
149 + 9479 = 9628
167 + 9461 = 9628

Showing the first eight; more decompositions exist.
