Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526968, here are decompositions:

  • 29 + 31526939 = 31526968
  • 41 + 31526927 = 31526968
  • 47 + 31526921 = 31526968
  • 89 + 31526879 = 31526968
  • 149 + 31526819 = 31526968
  • 191 + 31526777 = 31526968
  • 197 + 31526771 = 31526968
  • 479 + 31526489 = 31526968

Showing the first eight; more decompositions exist.
