Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524078, here are decompositions:

  • 29 + 31524049 = 31524078
  • 31 + 31524047 = 31524078
  • 67 + 31524011 = 31524078
  • 137 + 31523941 = 31524078
  • 139 + 31523939 = 31524078
  • 197 + 31523881 = 31524078
  • 227 + 31523851 = 31524078
  • 239 + 31523839 = 31524078

Showing the first eight; more decompositions exist.
