Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524858, here are decompositions:

  • 19 + 31524839 = 31524858
  • 61 + 31524797 = 31524858
  • 67 + 31524791 = 31524858
  • 137 + 31524721 = 31524858
  • 181 + 31524677 = 31524858
  • 251 + 31524607 = 31524858
  • 271 + 31524587 = 31524858
  • 317 + 31524541 = 31524858

Showing the first eight; more decompositions exist.
