Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467912, here are decompositions:

  • 13 + 31467899 = 31467912
  • 19 + 31467893 = 31467912
  • 59 + 31467853 = 31467912
  • 83 + 31467829 = 31467912
  • 101 + 31467811 = 31467912
  • 103 + 31467809 = 31467912
  • 149 + 31467763 = 31467912
  • 191 + 31467721 = 31467912

Showing the first eight; more decompositions exist.
