Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7320, here are decompositions:

11 + 7309 = 7320
13 + 7307 = 7320
23 + 7297 = 7320
37 + 7283 = 7320
67 + 7253 = 7320
73 + 7247 = 7320
83 + 7237 = 7320
101 + 7219 = 7320

Showing the first eight; more decompositions exist.
