Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998550, here are decompositions:

  • 11 + 998539 = 998550
  • 13 + 998537 = 998550
  • 23 + 998527 = 998550
  • 37 + 998513 = 998550
  • 53 + 998497 = 998550
  • 79 + 998471 = 998550
  • 107 + 998443 = 998550
  • 127 + 998423 = 998550

Showing the first eight; more decompositions exist.
