Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489798, here are decompositions:

5 + 489793 = 489798
7 + 489791 = 489798
37 + 489761 = 489798
107 + 489691 = 489798
109 + 489689 = 489798
139 + 489659 = 489798
167 + 489631 = 489798
227 + 489571 = 489798

Showing the first eight; more decompositions exist.
