Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516620, here are decompositions:

  • 3 + 516617 = 516620
  • 31 + 516589 = 516620
  • 79 + 516541 = 516620
  • 103 + 516517 = 516620
  • 127 + 516493 = 516620
  • 151 + 516469 = 516620
  • 163 + 516457 = 516620
  • 199 + 516421 = 516620

Showing the first eight; more decompositions exist.
