Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526860, here are decompositions:

  • 41 + 31526819 = 31526860
  • 83 + 31526777 = 31526860
  • 89 + 31526771 = 31526860
  • 107 + 31526753 = 31526860
  • 137 + 31526723 = 31526860
  • 191 + 31526669 = 31526860
  • 227 + 31526633 = 31526860
  • 257 + 31526603 = 31526860

Showing the first eight; more decompositions exist.
