Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526916, here are decompositions:

  • 13 + 31526903 = 31526916
  • 17 + 31526899 = 31526916
  • 23 + 31526893 = 31526916
  • 37 + 31526879 = 31526916
  • 53 + 31526863 = 31526916
  • 97 + 31526819 = 31526916
  • 107 + 31526809 = 31526916
  • 139 + 31526777 = 31526916

Showing the first eight; more decompositions exist.
