Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9108, here are decompositions:

5 + 9103 = 9108
17 + 9091 = 9108
41 + 9067 = 9108
59 + 9049 = 9108
67 + 9041 = 9108
79 + 9029 = 9108
97 + 9011 = 9108
101 + 9007 = 9108

Showing the first eight; more decompositions exist.
