Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645458, here are decompositions:

  • 131 + 8645327 = 8645458
  • 191 + 8645267 = 8645458
  • 197 + 8645261 = 8645458
  • 317 + 8645141 = 8645458
  • 449 + 8645009 = 8645458
  • 467 + 8644991 = 8645458
  • 509 + 8644949 = 8645458
  • 659 + 8644799 = 8645458

Showing the first eight; more decompositions exist.
