Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727690, here are decompositions:

  • 17 + 8727673 = 8727690
  • 31 + 8727659 = 8727690
  • 47 + 8727643 = 8727690
  • 67 + 8727623 = 8727690
  • 71 + 8727619 = 8727690
  • 79 + 8727611 = 8727690
  • 89 + 8727601 = 8727690
  • 107 + 8727583 = 8727690

Showing the first eight; more decompositions exist.
