Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489158, here are decompositions:

31 + 489127 = 489158
97 + 489061 = 489158
139 + 489019 = 489158
157 + 489001 = 489158
199 + 488959 = 489158
211 + 488947 = 489158
331 + 488827 = 489158
337 + 488821 = 489158

Showing the first eight; more decompositions exist.
