Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526950, here are decompositions:

  • 11 + 31526939 = 31526950
  • 23 + 31526927 = 31526950
  • 29 + 31526921 = 31526950
  • 47 + 31526903 = 31526950
  • 71 + 31526879 = 31526950
  • 131 + 31526819 = 31526950
  • 173 + 31526777 = 31526950
  • 179 + 31526771 = 31526950

Showing the first eight; more decompositions exist.
