Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749686, here are decompositions:

  • 17 + 8749669 = 8749686
  • 59 + 8749627 = 8749686
  • 73 + 8749613 = 8749686
  • 79 + 8749607 = 8749686
  • 83 + 8749603 = 8749686
  • 97 + 8749589 = 8749686
  • 107 + 8749579 = 8749686
  • 137 + 8749549 = 8749686

Showing the first eight; more decompositions exist.
