Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516786, here are decompositions:

  • 29 + 516757 = 516786
  • 59 + 516727 = 516786
  • 73 + 516713 = 516786
  • 97 + 516689 = 516786
  • 107 + 516679 = 516786
  • 113 + 516673 = 516786
  • 163 + 516623 = 516786
  • 167 + 516619 = 516786

Showing the first eight; more decompositions exist.
