Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989860, here are decompositions:

  • 23 + 989837 = 989860
  • 29 + 989831 = 989860
  • 83 + 989777 = 989860
  • 107 + 989753 = 989860
  • 173 + 989687 = 989860
  • 197 + 989663 = 989860
  • 281 + 989579 = 989860
  • 353 + 989507 = 989860

Showing the first eight; more decompositions exist.
