Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18248, here are decompositions:

19 + 18229 = 18248
31 + 18217 = 18248
37 + 18211 = 18248
67 + 18181 = 18248
79 + 18169 = 18248
127 + 18121 = 18248
151 + 18097 = 18248
199 + 18049 = 18248

Showing the first eight; more decompositions exist.
