Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690620, here are decompositions:

  • 17 + 8690603 = 8690620
  • 53 + 8690567 = 8690620
  • 89 + 8690531 = 8690620
  • 131 + 8690489 = 8690620
  • 167 + 8690453 = 8690620
  • 233 + 8690387 = 8690620
  • 269 + 8690351 = 8690620
  • 317 + 8690303 = 8690620

Showing the first eight; more decompositions exist.
