Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523946, here are decompositions:

  • 5 + 31523941 = 31523946
  • 7 + 31523939 = 31523946
  • 29 + 31523917 = 31523946
  • 107 + 31523839 = 31523946
  • 193 + 31523753 = 31523946
  • 197 + 31523749 = 31523946
  • 239 + 31523707 = 31523946
  • 277 + 31523669 = 31523946

Showing the first eight; more decompositions exist.
