Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982428, here are decompositions:

47 + 982381 = 982428
89 + 982339 = 982428
107 + 982321 = 982428
127 + 982301 = 982428
157 + 982271 = 982428
197 + 982231 = 982428
211 + 982217 = 982428
241 + 982187 = 982428

Showing the first eight; more decompositions exist.
