Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532976, here are decompositions:

  • 5 + 31532971 = 31532976
  • 17 + 31532959 = 31532976
  • 37 + 31532939 = 31532976
  • 53 + 31532923 = 31532976
  • 103 + 31532873 = 31532976
  • 109 + 31532867 = 31532976
  • 113 + 31532863 = 31532976
  • 199 + 31532777 = 31532976

Showing the first eight; more decompositions exist.
