Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989770, here are decompositions:

  • 17 + 989753 = 989770
  • 83 + 989687 = 989770
  • 107 + 989663 = 989770
  • 191 + 989579 = 989770
  • 263 + 989507 = 989770
  • 293 + 989477 = 989770
  • 347 + 989423 = 989770
  • 359 + 989411 = 989770

Showing the first eight; more decompositions exist.
