Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689638, here are decompositions:

  • 11 + 8689627 = 8689638
  • 29 + 8689609 = 8689638
  • 47 + 8689591 = 8689638
  • 101 + 8689537 = 8689638
  • 109 + 8689529 = 8689638
  • 149 + 8689489 = 8689638
  • 157 + 8689481 = 8689638
  • 239 + 8689399 = 8689638

Showing the first eight; more decompositions exist.
