Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39470, here are decompositions:

  • 19 + 39451 = 39470
  • 31 + 39439 = 39470
  • 61 + 39409 = 39470
  • 73 + 39397 = 39470
  • 97 + 39373 = 39470
  • 103 + 39367 = 39470
  • 127 + 39343 = 39470
  • 157 + 39313 = 39470

Showing the first eight; more decompositions exist.
