Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534078, here are decompositions:

  • 5 + 31534073 = 31534078
  • 11 + 31534067 = 31534078
  • 167 + 31533911 = 31534078
  • 239 + 31533839 = 31534078
  • 419 + 31533659 = 31534078
  • 467 + 31533611 = 31534078
  • 479 + 31533599 = 31534078
  • 491 + 31533587 = 31534078

Showing the first eight; more decompositions exist.
