Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7146, here are decompositions:

17 + 7129 = 7146
19 + 7127 = 7146
37 + 7109 = 7146
43 + 7103 = 7146
67 + 7079 = 7146
89 + 7057 = 7146
103 + 7043 = 7146
107 + 7039 = 7146

Showing the first eight; more decompositions exist.
