Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525860, here are decompositions:

  • 11 + 31525849 = 31525860
  • 19 + 31525841 = 31525860
  • 43 + 31525817 = 31525860
  • 61 + 31525799 = 31525860
  • 73 + 31525787 = 31525860
  • 83 + 31525777 = 31525860
  • 89 + 31525771 = 31525860
  • 97 + 31525763 = 31525860

Showing the first eight; more decompositions exist.
