Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697520, here are decompositions:

  • 11 + 8697509 = 8697520
  • 17 + 8697503 = 8697520
  • 113 + 8697407 = 8697520
  • 131 + 8697389 = 8697520
  • 257 + 8697263 = 8697520
  • 281 + 8697239 = 8697520
  • 431 + 8697089 = 8697520
  • 521 + 8696999 = 8697520

Showing the first eight; more decompositions exist.
