Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624, here are decompositions:

  • 43 + 8581 = 8624
  • 61 + 8563 = 8624
  • 97 + 8527 = 8624
  • 103 + 8521 = 8624
  • 157 + 8467 = 8624
  • 163 + 8461 = 8624
  • 181 + 8443 = 8624
  • 193 + 8431 = 8624

Showing the first eight; more decompositions exist.
