Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524876, here are decompositions:

  • 13 + 31524863 = 31524876
  • 37 + 31524839 = 31524876
  • 67 + 31524809 = 31524876
  • 79 + 31524797 = 31524876
  • 83 + 31524793 = 31524876
  • 109 + 31524767 = 31524876
  • 113 + 31524763 = 31524876
  • 199 + 31524677 = 31524876

Showing the first eight; more decompositions exist.
