Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7328, here are decompositions:

7 + 7321 = 7328
19 + 7309 = 7328
31 + 7297 = 7328
109 + 7219 = 7328
151 + 7177 = 7328
199 + 7129 = 7328
271 + 7057 = 7328
331 + 6997 = 7328

Showing the first eight; more decompositions exist.
