Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30312, here are decompositions:

5 + 30307 = 30312
19 + 30293 = 30312
41 + 30271 = 30312
43 + 30269 = 30312
53 + 30259 = 30312
59 + 30253 = 30312
71 + 30241 = 30312
89 + 30223 = 30312

Showing the first eight; more decompositions exist.
