Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30022, here are decompositions:

11 + 30011 = 30022
101 + 29921 = 30022
149 + 29873 = 30022
233 + 29789 = 30022
263 + 29759 = 30022
269 + 29753 = 30022
281 + 29741 = 30022
353 + 29669 = 30022

Showing the first eight; more decompositions exist.
