Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8695780, here are decompositions:

  • 11 + 8695769 = 8695780
  • 53 + 8695727 = 8695780
  • 113 + 8695667 = 8695780
  • 179 + 8695601 = 8695780
  • 251 + 8695529 = 8695780
  • 347 + 8695433 = 8695780
  • 461 + 8695319 = 8695780
  • 479 + 8695301 = 8695780

Showing the first eight; more decompositions exist.
