Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697620, here are decompositions:

  • 7 + 8697613 = 8697620
  • 13 + 8697607 = 8697620
  • 109 + 8697511 = 8697620
  • 241 + 8697379 = 8697620
  • 277 + 8697343 = 8697620
  • 307 + 8697313 = 8697620
  • 367 + 8697253 = 8697620
  • 457 + 8697163 = 8697620

Showing the first eight; more decompositions exist.
