Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489230, here are decompositions:

13 + 489217 = 489230
73 + 489157 = 489230
97 + 489133 = 489230
103 + 489127 = 489230
211 + 489019 = 489230
229 + 489001 = 489230
271 + 488959 = 489230
283 + 488947 = 489230

Showing the first eight; more decompositions exist.
