Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82866, here are decompositions:

  • 19 + 82847 = 82866
  • 29 + 82837 = 82866
  • 53 + 82813 = 82866
  • 67 + 82799 = 82866
  • 73 + 82793 = 82866
  • 79 + 82787 = 82866
  • 103 + 82763 = 82866
  • 107 + 82759 = 82866

Showing the first eight; more decompositions exist.
