Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546550, here are decompositions:

  • 67 + 31546483 = 31546550
  • 157 + 31546393 = 31546550
  • 163 + 31546387 = 31546550
  • 181 + 31546369 = 31546550
  • 199 + 31546351 = 31546550
  • 271 + 31546279 = 31546550
  • 283 + 31546267 = 31546550
  • 397 + 31546153 = 31546550

Showing the first eight; more decompositions exist.
