Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489290, here are decompositions:

7 + 489283 = 489290
73 + 489217 = 489290
157 + 489133 = 489290
163 + 489127 = 489290
181 + 489109 = 489290
229 + 489061 = 489290
271 + 489019 = 489290
331 + 488959 = 489290

Showing the first eight; more decompositions exist.
