Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985216, here are decompositions:

  • 3 + 985213 = 985216
  • 107 + 985109 = 985216
  • 137 + 985079 = 985216
  • 257 + 984959 = 985216
  • 269 + 984947 = 985216
  • 293 + 984923 = 985216
  • 467 + 984749 = 985216
  • 509 + 984707 = 985216

Showing the first eight; more decompositions exist.
