Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524030, here are decompositions:

  • 7 + 31524023 = 31524030
  • 17 + 31524013 = 31524030
  • 19 + 31524011 = 31524030
  • 89 + 31523941 = 31524030
  • 113 + 31523917 = 31524030
  • 149 + 31523881 = 31524030
  • 179 + 31523851 = 31524030
  • 191 + 31523839 = 31524030

Showing the first eight; more decompositions exist.
