Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7184, here are decompositions:

7 + 7177 = 7184
127 + 7057 = 7184
157 + 7027 = 7184
193 + 6991 = 7184
223 + 6961 = 7184
277 + 6907 = 7184
313 + 6871 = 7184
421 + 6763 = 7184

Showing the first eight; more decompositions exist.
