Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526884, here are decompositions:

  • 3 + 31526881 = 31526884
  • 5 + 31526879 = 31526884
  • 107 + 31526777 = 31526884
  • 113 + 31526771 = 31526884
  • 131 + 31526753 = 31526884
  • 251 + 31526633 = 31526884
  • 281 + 31526603 = 31526884
  • 461 + 31526423 = 31526884

Showing the first eight; more decompositions exist.
