Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9144, here are decompositions:

7 + 9137 = 9144
11 + 9133 = 9144
17 + 9127 = 9144
41 + 9103 = 9144
53 + 9091 = 9144
101 + 9043 = 9144
103 + 9041 = 9144
131 + 9013 = 9144

Showing the first eight; more decompositions exist.
