Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584300, here are decompositions:

  • 19 + 31584281 = 31584300
  • 37 + 31584263 = 31584300
  • 53 + 31584247 = 31584300
  • 67 + 31584233 = 31584300
  • 89 + 31584211 = 31584300
  • 103 + 31584197 = 31584300
  • 107 + 31584193 = 31584300
  • 109 + 31584191 = 31584300

Showing the first eight; more decompositions exist.
