Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998650, here are decompositions:

  • 17 + 998633 = 998650
  • 89 + 998561 = 998650
  • 113 + 998537 = 998650
  • 137 + 998513 = 998650
  • 179 + 998471 = 998650
  • 227 + 998423 = 998650
  • 239 + 998411 = 998650
  • 251 + 998399 = 998650

Showing the first eight; more decompositions exist.
