Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527868, here are decompositions:

  • 41 + 31527827 = 31527868
  • 167 + 31527701 = 31527868
  • 179 + 31527689 = 31527868
  • 191 + 31527677 = 31527868
  • 347 + 31527521 = 31527868
  • 461 + 31527407 = 31527868
  • 479 + 31527389 = 31527868
  • 557 + 31527311 = 31527868

Showing the first eight; more decompositions exist.
