Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39428, here are decompositions:

19 + 39409 = 39428
31 + 39397 = 39428
61 + 39367 = 39428
127 + 39301 = 39428
199 + 39229 = 39428
211 + 39217 = 39428
229 + 39199 = 39428
271 + 39157 = 39428

Showing the first eight; more decompositions exist.
