Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7154, here are decompositions:

3 + 7151 = 7154
97 + 7057 = 7154
127 + 7027 = 7154
157 + 6997 = 7154
163 + 6991 = 7154
193 + 6961 = 7154
271 + 6883 = 7154
283 + 6871 = 7154

Showing the first eight; more decompositions exist.
