Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8402, here are decompositions:

  • 13 + 8389 = 8402
  • 73 + 8329 = 8402
  • 109 + 8293 = 8402
  • 139 + 8263 = 8402
  • 181 + 8221 = 8402
  • 193 + 8209 = 8402
  • 211 + 8191 = 8402
  • 223 + 8179 = 8402

Showing the first eight; more decompositions exist.
