Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660680, here are decompositions:

  • 23 + 8660657 = 8660680
  • 71 + 8660609 = 8660680
  • 101 + 8660579 = 8660680
  • 137 + 8660543 = 8660680
  • 173 + 8660507 = 8660680
  • 257 + 8660423 = 8660680
  • 293 + 8660387 = 8660680
  • 311 + 8660369 = 8660680

Showing the first eight; more decompositions exist.
