Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729542, here are decompositions:

  • 113 + 8729429 = 8729542
  • 131 + 8729411 = 8729542
  • 233 + 8729309 = 8729542
  • 251 + 8729291 = 8729542
  • 293 + 8729249 = 8729542
  • 359 + 8729183 = 8729542
  • 401 + 8729141 = 8729542
  • 443 + 8729099 = 8729542

Showing the first eight; more decompositions exist.
