Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82786, here are decompositions:

  • 5 + 82781 = 82786
  • 23 + 82763 = 82786
  • 29 + 82757 = 82786
  • 59 + 82727 = 82786
  • 167 + 82619 = 82786
  • 173 + 82613 = 82786
  • 227 + 82559 = 82786
  • 257 + 82529 = 82786

Showing the first eight; more decompositions exist.
