Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7340, here are decompositions:

7 + 7333 = 7340
19 + 7321 = 7340
31 + 7309 = 7340
43 + 7297 = 7340
97 + 7243 = 7340
103 + 7237 = 7340
127 + 7213 = 7340
163 + 7177 = 7340

Showing the first eight; more decompositions exist.
