Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7158, here are decompositions:

7 + 7151 = 7158
29 + 7129 = 7158
31 + 7127 = 7158
37 + 7121 = 7158
79 + 7079 = 7158
89 + 7069 = 7158
101 + 7057 = 7158
131 + 7027 = 7158

Showing the first eight; more decompositions exist.
