Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30430, here are decompositions:

3 + 30427 = 30430
41 + 30389 = 30430
83 + 30347 = 30430
89 + 30341 = 30430
107 + 30323 = 30430
137 + 30293 = 30430
227 + 30203 = 30430
233 + 30197 = 30430

Showing the first eight; more decompositions exist.
