Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15320, here are decompositions:

7 + 15313 = 15320
13 + 15307 = 15320
31 + 15289 = 15320
43 + 15277 = 15320
61 + 15259 = 15320
79 + 15241 = 15320
103 + 15217 = 15320
127 + 15193 = 15320

Showing the first eight; more decompositions exist.
