Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489994, here are decompositions:

5 + 489989 = 489994
17 + 489977 = 489994
53 + 489941 = 489994
83 + 489911 = 489994
107 + 489887 = 489994
191 + 489803 = 489994
233 + 489761 = 489994
251 + 489743 = 489994

Showing the first eight; more decompositions exist.
