Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527856, here are decompositions:

  • 29 + 31527827 = 31527856
  • 167 + 31527689 = 31527856
  • 179 + 31527677 = 31527856
  • 197 + 31527659 = 31527856
  • 359 + 31527497 = 31527856
  • 443 + 31527413 = 31527856
  • 449 + 31527407 = 31527856
  • 467 + 31527389 = 31527856

Showing the first eight; more decompositions exist.
