Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526794, here are decompositions:

  • 3 + 31526791 = 31526794
  • 17 + 31526777 = 31526794
  • 23 + 31526771 = 31526794
  • 41 + 31526753 = 31526794
  • 71 + 31526723 = 31526794
  • 191 + 31526603 = 31526794
  • 317 + 31526477 = 31526794
  • 443 + 31526351 = 31526794

Showing the first eight; more decompositions exist.
