Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9140, here are decompositions:

3 + 9137 = 9140
7 + 9133 = 9140
13 + 9127 = 9140
31 + 9109 = 9140
37 + 9103 = 9140
73 + 9067 = 9140
97 + 9043 = 9140
127 + 9013 = 9140

Showing the first eight; more decompositions exist.
