Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730040, here are decompositions:

  • 41 + 8729999 = 8730040
  • 101 + 8729939 = 8730040
  • 173 + 8729867 = 8730040
  • 191 + 8729849 = 8730040
  • 239 + 8729801 = 8730040
  • 311 + 8729729 = 8730040
  • 359 + 8729681 = 8730040
  • 419 + 8729621 = 8730040

Showing the first eight; more decompositions exist.
