Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624870, here are decompositions:

  • 97 + 8624773 = 8624870
  • 157 + 8624713 = 8624870
  • 193 + 8624677 = 8624870
  • 271 + 8624599 = 8624870
  • 367 + 8624503 = 8624870
  • 421 + 8624449 = 8624870
  • 487 + 8624383 = 8624870
  • 547 + 8624323 = 8624870

Showing the first eight; more decompositions exist.
