Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647198, here are decompositions:

  • 5 + 8647193 = 8647198
  • 17 + 8647181 = 8647198
  • 41 + 8647157 = 8647198
  • 59 + 8647139 = 8647198
  • 71 + 8647127 = 8647198
  • 107 + 8647091 = 8647198
  • 137 + 8647061 = 8647198
  • 167 + 8647031 = 8647198

Showing the first eight; more decompositions exist.
