Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82290, here are decompositions:

  • 11 + 82279 = 82290
  • 23 + 82267 = 82290
  • 29 + 82261 = 82290
  • 53 + 82237 = 82290
  • 59 + 82231 = 82290
  • 67 + 82223 = 82290
  • 71 + 82219 = 82290
  • 73 + 82217 = 82290

Showing the first eight; more decompositions exist.
