Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710720, here are decompositions:

  • 3 + 8710717 = 8710720
  • 17 + 8710703 = 8710720
  • 41 + 8710679 = 8710720
  • 71 + 8710649 = 8710720
  • 89 + 8710631 = 8710720
  • 131 + 8710589 = 8710720
  • 149 + 8710571 = 8710720
  • 173 + 8710547 = 8710720

Showing the first eight; more decompositions exist.
