Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7310, here are decompositions:

3 + 7307 = 7310
13 + 7297 = 7310
67 + 7243 = 7310
73 + 7237 = 7310
97 + 7213 = 7310
103 + 7207 = 7310
151 + 7159 = 7310
181 + 7129 = 7310

Showing the first eight; more decompositions exist.
