Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15284, here are decompositions:

7 + 15277 = 15284
13 + 15271 = 15284
43 + 15241 = 15284
67 + 15217 = 15284
97 + 15187 = 15284
163 + 15121 = 15284
193 + 15091 = 15284
211 + 15073 = 15284

Showing the first eight; more decompositions exist.
