Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30658, here are decompositions:

101 + 30557 = 30658
149 + 30509 = 30658
167 + 30491 = 30658
191 + 30467 = 30658
227 + 30431 = 30658
269 + 30389 = 30658
311 + 30347 = 30658
317 + 30341 = 30658

Showing the first eight; more decompositions exist.
