Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9618, here are decompositions:

5 + 9613 = 9618
17 + 9601 = 9618
31 + 9587 = 9618
67 + 9551 = 9618
71 + 9547 = 9618
79 + 9539 = 9618
97 + 9521 = 9618
107 + 9511 = 9618

Showing the first eight; more decompositions exist.
