Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533966, here are decompositions:

  • 7 + 31533959 = 31533966
  • 17 + 31533949 = 31533966
  • 43 + 31533923 = 31533966
  • 47 + 31533919 = 31533966
  • 127 + 31533839 = 31533966
  • 137 + 31533829 = 31533966
  • 193 + 31533773 = 31533966
  • 197 + 31533769 = 31533966

Showing the first eight; more decompositions exist.
