Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728528, here are decompositions:

  • 47 + 8728481 = 8728528
  • 71 + 8728457 = 8728528
  • 101 + 8728427 = 8728528
  • 131 + 8728397 = 8728528
  • 197 + 8728331 = 8728528
  • 239 + 8728289 = 8728528
  • 317 + 8728211 = 8728528
  • 359 + 8728169 = 8728528

Showing the first eight; more decompositions exist.
