Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620010, here are decompositions:

  • 17 + 31619993 = 31620010
  • 29 + 31619981 = 31620010
  • 167 + 31619843 = 31620010
  • 239 + 31619771 = 31620010
  • 251 + 31619759 = 31620010
  • 269 + 31619741 = 31620010
  • 293 + 31619717 = 31620010
  • 449 + 31619561 = 31620010

Showing the first eight; more decompositions exist.
