Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523976, here are decompositions:

  • 23 + 31523953 = 31523976
  • 37 + 31523939 = 31523976
  • 59 + 31523917 = 31523976
  • 137 + 31523839 = 31523976
  • 173 + 31523803 = 31523976
  • 223 + 31523753 = 31523976
  • 227 + 31523749 = 31523976
  • 269 + 31523707 = 31523976

Showing the first eight; more decompositions exist.
