Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524946, here are decompositions:

  • 53 + 31524893 = 31524946
  • 83 + 31524863 = 31524946
  • 107 + 31524839 = 31524946
  • 137 + 31524809 = 31524946
  • 149 + 31524797 = 31524946
  • 179 + 31524767 = 31524946
  • 269 + 31524677 = 31524946
  • 359 + 31524587 = 31524946

Showing the first eight; more decompositions exist.
