Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617218, here are decompositions:

  • 7 + 8617211 = 8617218
  • 11 + 8617207 = 8617218
  • 17 + 8617201 = 8617218
  • 31 + 8617187 = 8617218
  • 41 + 8617177 = 8617218
  • 47 + 8617171 = 8617218
  • 89 + 8617129 = 8617218
  • 109 + 8617109 = 8617218

Showing the first eight; more decompositions exist.
