Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728750, here are decompositions:

  • 29 + 8728721 = 8728750
  • 59 + 8728691 = 8728750
  • 71 + 8728679 = 8728750
  • 101 + 8728649 = 8728750
  • 179 + 8728571 = 8728750
  • 269 + 8728481 = 8728750
  • 293 + 8728457 = 8728750
  • 353 + 8728397 = 8728750

Showing the first eight; more decompositions exist.
