Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745686, here are decompositions:

  • 3 + 8745683 = 8745686
  • 7 + 8745679 = 8745686
  • 73 + 8745613 = 8745686
  • 139 + 8745547 = 8745686
  • 163 + 8745523 = 8745686
  • 193 + 8745493 = 8745686
  • 379 + 8745307 = 8745686
  • 463 + 8745223 = 8745686

Showing the first eight; more decompositions exist.
