Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715278, here are decompositions:

  • 97 + 8715181 = 8715278
  • 127 + 8715151 = 8715278
  • 199 + 8715079 = 8715278
  • 331 + 8714947 = 8715278
  • 337 + 8714941 = 8715278
  • 421 + 8714857 = 8715278
  • 457 + 8714821 = 8715278
  • 499 + 8714779 = 8715278

Showing the first eight; more decompositions exist.
