Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525896, here are decompositions:

  • 5 + 31525891 = 31525896
  • 7 + 31525889 = 31525896
  • 47 + 31525849 = 31525896
  • 79 + 31525817 = 31525896
  • 97 + 31525799 = 31525896
  • 109 + 31525787 = 31525896
  • 113 + 31525783 = 31525896
  • 173 + 31525723 = 31525896

Showing the first eight; more decompositions exist.
