Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670438, here are decompositions:

  • 5 + 8670433 = 8670438
  • 31 + 8670407 = 8670438
  • 41 + 8670397 = 8670438
  • 67 + 8670371 = 8670438
  • 107 + 8670331 = 8670438
  • 137 + 8670301 = 8670438
  • 157 + 8670281 = 8670438
  • 181 + 8670257 = 8670438

Showing the first eight; more decompositions exist.
