Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546470, here are decompositions:

  • 13 + 31546457 = 31546470
  • 19 + 31546451 = 31546470
  • 83 + 31546387 = 31546470
  • 101 + 31546369 = 31546470
  • 167 + 31546303 = 31546470
  • 191 + 31546279 = 31546470
  • 239 + 31546231 = 31546470
  • 271 + 31546199 = 31546470

Showing the first eight; more decompositions exist.
