Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489856, here are decompositions:

  • 5 + 489851 = 489856
  • 23 + 489833 = 489856
  • 53 + 489803 = 489856
  • 113 + 489743 = 489856
  • 167 + 489689 = 489856
  • 179 + 489677 = 489856
  • 197 + 489659 = 489856
  • 317 + 489539 = 489856

Showing the first eight; more decompositions exist.
