Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30358, here are decompositions:

11 + 30347 = 30358
17 + 30341 = 30358
89 + 30269 = 30358
197 + 30161 = 30358
239 + 30119 = 30358
269 + 30089 = 30358
311 + 30047 = 30358
347 + 30011 = 30358

Showing the first eight; more decompositions exist.
