Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30518, here are decompositions:

127 + 30391 = 30518
151 + 30367 = 30518
199 + 30319 = 30518
211 + 30307 = 30518
277 + 30241 = 30518
307 + 30211 = 30518
331 + 30187 = 30518
337 + 30181 = 30518

Showing the first eight; more decompositions exist.
