Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670520, here are decompositions:

  • 11 + 8670509 = 8670520
  • 17 + 8670503 = 8670520
  • 29 + 8670491 = 8670520
  • 113 + 8670407 = 8670520
  • 149 + 8670371 = 8670520
  • 167 + 8670353 = 8670520
  • 239 + 8670281 = 8670520
  • 263 + 8670257 = 8670520

Showing the first eight; more decompositions exist.
