Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545834, here are decompositions:

  • 71 + 31545763 = 31545834
  • 97 + 31545737 = 31545834
  • 167 + 31545667 = 31545834
  • 193 + 31545641 = 31545834
  • 211 + 31545623 = 31545834
  • 223 + 31545611 = 31545834
  • 227 + 31545607 = 31545834
  • 347 + 31545487 = 31545834

Showing the first eight; more decompositions exist.
