Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622928, here are decompositions:

  • 5 + 31622923 = 31622928
  • 47 + 31622881 = 31622928
  • 149 + 31622779 = 31622928
  • 151 + 31622777 = 31622928
  • 199 + 31622729 = 31622928
  • 229 + 31622699 = 31622928
  • 241 + 31622687 = 31622928
  • 257 + 31622671 = 31622928

Showing the first eight; more decompositions exist.
