Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938620, here are decompositions:

  • 3 + 938617 = 938620
  • 29 + 938591 = 938620
  • 47 + 938573 = 938620
  • 83 + 938537 = 938620
  • 113 + 938507 = 938620
  • 167 + 938453 = 938620
  • 173 + 938447 = 938620
  • 227 + 938393 = 938620

Showing the first eight; more decompositions exist.
