Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489938, here are decompositions:

37 + 489901 = 489938
67 + 489871 = 489938
139 + 489799 = 489938
307 + 489631 = 489938
367 + 489571 = 489938
409 + 489529 = 489938
499 + 489439 = 489938
571 + 489367 = 489938

Showing the first eight; more decompositions exist.
