Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700680, here are decompositions:

  • 31 + 8700649 = 8700680
  • 151 + 8700529 = 8700680
  • 223 + 8700457 = 8700680
  • 397 + 8700283 = 8700680
  • 487 + 8700193 = 8700680
  • 601 + 8700079 = 8700680
  • 643 + 8700037 = 8700680
  • 661 + 8700019 = 8700680

Showing the first eight; more decompositions exist.
