Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30390, here are decompositions:

23 + 30367 = 30390
43 + 30347 = 30390
67 + 30323 = 30390
71 + 30319 = 30390
83 + 30307 = 30390
97 + 30293 = 30390
131 + 30259 = 30390
137 + 30253 = 30390

Showing the first eight; more decompositions exist.
