Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529928, here are decompositions:

  • 5 + 31529923 = 31529928
  • 29 + 31529899 = 31529928
  • 37 + 31529891 = 31529928
  • 47 + 31529881 = 31529928
  • 109 + 31529819 = 31529928
  • 179 + 31529749 = 31529928
  • 211 + 31529717 = 31529928
  • 251 + 31529677 = 31529928

Showing the first eight; more decompositions exist.
