Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489428, here are decompositions:

19 + 489409 = 489428
61 + 489367 = 489428
67 + 489361 = 489428
211 + 489217 = 489428
271 + 489157 = 489428
367 + 489061 = 489428
409 + 489019 = 489428
601 + 488827 = 489428

Showing the first eight; more decompositions exist.
