Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526902, here are decompositions:

  • 3 + 31526899 = 31526902
  • 23 + 31526879 = 31526902
  • 83 + 31526819 = 31526902
  • 131 + 31526771 = 31526902
  • 149 + 31526753 = 31526902
  • 179 + 31526723 = 31526902
  • 233 + 31526669 = 31526902
  • 269 + 31526633 = 31526902

Showing the first eight; more decompositions exist.
