Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30574, here are decompositions:

17 + 30557 = 30574
83 + 30491 = 30574
107 + 30467 = 30574
227 + 30347 = 30574
233 + 30341 = 30574
251 + 30323 = 30574
281 + 30293 = 30574
461 + 30113 = 30574

Showing the first eight; more decompositions exist.
