Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7148, here are decompositions:

19 + 7129 = 7148
79 + 7069 = 7148
109 + 7039 = 7148
151 + 6997 = 7148
157 + 6991 = 7148
181 + 6967 = 7148
199 + 6949 = 7148
241 + 6907 = 7148

Showing the first eight; more decompositions exist.
