Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621214, here are decompositions:

  • 5 + 8621209 = 8621214
  • 13 + 8621201 = 8621214
  • 31 + 8621183 = 8621214
  • 61 + 8621153 = 8621214
  • 67 + 8621147 = 8621214
  • 71 + 8621143 = 8621214
  • 113 + 8621101 = 8621214
  • 127 + 8621087 = 8621214

Showing the first eight; more decompositions exist.
