Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684218, here are decompositions:

  • 5 + 8684213 = 8684218
  • 17 + 8684201 = 8684218
  • 29 + 8684189 = 8684218
  • 41 + 8684177 = 8684218
  • 47 + 8684171 = 8684218
  • 71 + 8684147 = 8684218
  • 107 + 8684111 = 8684218
  • 149 + 8684069 = 8684218

Showing the first eight; more decompositions exist.
