Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470, here are decompositions:

  • 73 + 31397 = 31470
  • 79 + 31391 = 31470
  • 83 + 31387 = 31470
  • 113 + 31357 = 31470
  • 137 + 31333 = 31470
  • 149 + 31321 = 31470
  • 151 + 31319 = 31470
  • 163 + 31307 = 31470

Showing the first eight; more decompositions exist.
