Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43470, here are decompositions:

  • 13 + 43457 = 43470
  • 19 + 43451 = 43470
  • 29 + 43441 = 43470
  • 43 + 43427 = 43470
  • 59 + 43411 = 43470
  • 67 + 43403 = 43470
  • 71 + 43399 = 43470
  • 73 + 43397 = 43470

Showing the first eight; more decompositions exist.
