Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526992, here are decompositions:

  • 53 + 31526939 = 31526992
  • 71 + 31526921 = 31526992
  • 89 + 31526903 = 31526992
  • 113 + 31526879 = 31526992
  • 173 + 31526819 = 31526992
  • 239 + 31526753 = 31526992
  • 269 + 31526723 = 31526992
  • 359 + 31526633 = 31526992

Showing the first eight; more decompositions exist.
