Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489718, here are decompositions:

29 + 489689 = 489718
41 + 489677 = 489718
59 + 489659 = 489718
167 + 489551 = 489718
179 + 489539 = 489718
239 + 489479 = 489718
269 + 489449 = 489718
311 + 489407 = 489718

Showing the first eight; more decompositions exist.
