Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30386, here are decompositions:

19 + 30367 = 30386
67 + 30319 = 30386
73 + 30313 = 30386
79 + 30307 = 30386
127 + 30259 = 30386
163 + 30223 = 30386
199 + 30187 = 30386
277 + 30109 = 30386

Showing the first eight; more decompositions exist.
