Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30342, here are decompositions:

19 + 30323 = 30342
23 + 30319 = 30342
29 + 30313 = 30342
71 + 30271 = 30342
73 + 30269 = 30342
83 + 30259 = 30342
89 + 30253 = 30342
101 + 30241 = 30342

Showing the first eight; more decompositions exist.
