Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30320, here are decompositions:

7 + 30313 = 30320
13 + 30307 = 30320
61 + 30259 = 30320
67 + 30253 = 30320
79 + 30241 = 30320
97 + 30223 = 30320
109 + 30211 = 30320
139 + 30181 = 30320

Showing the first eight; more decompositions exist.
