Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489998, here are decompositions:

37 + 489961 = 489998
97 + 489901 = 489998
127 + 489871 = 489998
151 + 489847 = 489998
181 + 489817 = 489998
199 + 489799 = 489998
307 + 489691 = 489998
367 + 489631 = 489998

Showing the first eight; more decompositions exist.
