Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989908, here are decompositions:

  • 71 + 989837 = 989908
  • 131 + 989777 = 989908
  • 347 + 989561 = 989908
  • 401 + 989507 = 989908
  • 431 + 989477 = 989908
  • 467 + 989441 = 989908
  • 587 + 989321 = 989908
  • 599 + 989309 = 989908

Showing the first eight; more decompositions exist.
