Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520716, here are decompositions:

  • 89 + 31520627 = 31520716
  • 137 + 31520579 = 31520716
  • 179 + 31520537 = 31520716
  • 197 + 31520519 = 31520716
  • 233 + 31520483 = 31520716
  • 263 + 31520453 = 31520716
  • 317 + 31520399 = 31520716
  • 599 + 31520117 = 31520716

Showing the first eight; more decompositions exist.
