Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622968, here are decompositions:

  • 17 + 31622951 = 31622968
  • 29 + 31622939 = 31622968
  • 131 + 31622837 = 31622968
  • 191 + 31622777 = 31622968
  • 227 + 31622741 = 31622968
  • 239 + 31622729 = 31622968
  • 269 + 31622699 = 31622968
  • 281 + 31622687 = 31622968

Showing the first eight; more decompositions exist.
