Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526824, here are decompositions:

  • 5 + 31526819 = 31526824
  • 47 + 31526777 = 31526824
  • 53 + 31526771 = 31526824
  • 71 + 31526753 = 31526824
  • 101 + 31526723 = 31526824
  • 191 + 31526633 = 31526824
  • 347 + 31526477 = 31526824
  • 401 + 31526423 = 31526824

Showing the first eight; more decompositions exist.
