Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715660, here are decompositions:

  • 7 + 8715653 = 8715660
  • 11 + 8715649 = 8715660
  • 13 + 8715647 = 8715660
  • 43 + 8715617 = 8715660
  • 59 + 8715601 = 8715660
  • 71 + 8715589 = 8715660
  • 73 + 8715587 = 8715660
  • 101 + 8715559 = 8715660

Showing the first eight; more decompositions exist.
