Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591664, here are decompositions:

  • 31 + 8591633 = 8591664
  • 41 + 8591623 = 8591664
  • 47 + 8591617 = 8591664
  • 61 + 8591603 = 8591664
  • 71 + 8591593 = 8591664
  • 101 + 8591563 = 8591664
  • 131 + 8591533 = 8591664
  • 157 + 8591507 = 8591664

Showing the first eight; more decompositions exist.
