Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489140, here are decompositions:

7 + 489133 = 489140
13 + 489127 = 489140
31 + 489109 = 489140
79 + 489061 = 489140
97 + 489043 = 489140
139 + 489001 = 489140
181 + 488959 = 489140
193 + 488947 = 489140

Showing the first eight; more decompositions exist.
