Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523948, here are decompositions:

  • 7 + 31523941 = 31523948
  • 31 + 31523917 = 31523948
  • 67 + 31523881 = 31523948
  • 97 + 31523851 = 31523948
  • 109 + 31523839 = 31523948
  • 199 + 31523749 = 31523948
  • 241 + 31523707 = 31523948
  • 349 + 31523599 = 31523948

Showing the first eight; more decompositions exist.
