Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29420, here are decompositions:

19 + 29401 = 29420
31 + 29389 = 29420
37 + 29383 = 29420
73 + 29347 = 29420
109 + 29311 = 29420
151 + 29269 = 29420
199 + 29221 = 29420
211 + 29209 = 29420

Showing the first eight; more decompositions exist.
