Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64470, here are decompositions:

  • 17 + 64453 = 64470
  • 19 + 64451 = 64470
  • 31 + 64439 = 64470
  • 37 + 64433 = 64470
  • 67 + 64403 = 64470
  • 71 + 64399 = 64470
  • 89 + 64381 = 64470
  • 97 + 64373 = 64470

Showing the first eight; more decompositions exist.
