Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9162, here are decompositions:

5 + 9157 = 9162
11 + 9151 = 9162
29 + 9133 = 9162
53 + 9109 = 9162
59 + 9103 = 9162
71 + 9091 = 9162
103 + 9059 = 9162
113 + 9049 = 9162

Showing the first eight; more decompositions exist.
