Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697642, here are decompositions:

  • 29 + 8697613 = 8697642
  • 43 + 8697599 = 8697642
  • 61 + 8697581 = 8697642
  • 103 + 8697539 = 8697642
  • 131 + 8697511 = 8697642
  • 139 + 8697503 = 8697642
  • 263 + 8697379 = 8697642
  • 379 + 8697263 = 8697642

Showing the first eight; more decompositions exist.
