Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489008, here are decompositions:

7 + 489001 = 489008
61 + 488947 = 489008
181 + 488827 = 489008
211 + 488797 = 489008
229 + 488779 = 489008
307 + 488701 = 489008
367 + 488641 = 489008
397 + 488611 = 489008

Showing the first eight; more decompositions exist.
