Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634, here are decompositions:

  • 5 + 8629 = 8634
  • 7 + 8627 = 8634
  • 11 + 8623 = 8634
  • 37 + 8597 = 8634
  • 53 + 8581 = 8634
  • 61 + 8573 = 8634
  • 71 + 8563 = 8634
  • 97 + 8537 = 8634

Showing the first eight; more decompositions exist.
