Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999936, here are decompositions:

  • 5 + 999931 = 999936
  • 19 + 999917 = 999936
  • 29 + 999907 = 999936
  • 53 + 999883 = 999936
  • 73 + 999863 = 999936
  • 83 + 999853 = 999936
  • 127 + 999809 = 999936
  • 163 + 999773 = 999936

Showing the first eight; more decompositions exist.
