Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169786, here are decompositions:

  • 3 + 169783 = 169786
  • 17 + 169769 = 169786
  • 53 + 169733 = 169786
  • 137 + 169649 = 169786
  • 179 + 169607 = 169786
  • 233 + 169553 = 169786
  • 263 + 169523 = 169786
  • 293 + 169493 = 169786

Showing the first eight; more decompositions exist.
