Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701686, here are decompositions:

  • 29 + 8701657 = 8701686
  • 43 + 8701643 = 8701686
  • 109 + 8701577 = 8701686
  • 127 + 8701559 = 8701686
  • 157 + 8701529 = 8701686
  • 167 + 8701519 = 8701686
  • 179 + 8701507 = 8701686
  • 193 + 8701493 = 8701686

Showing the first eight; more decompositions exist.
