Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536864, here are decompositions:

  • 17 + 31536847 = 31536864
  • 41 + 31536823 = 31536864
  • 43 + 31536821 = 31536864
  • 71 + 31536793 = 31536864
  • 131 + 31536733 = 31536864
  • 157 + 31536707 = 31536864
  • 167 + 31536697 = 31536864
  • 251 + 31536613 = 31536864

Showing the first eight; more decompositions exist.
