Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573936, here are decompositions:

  • 5 + 31573931 = 31573936
  • 83 + 31573853 = 31573936
  • 89 + 31573847 = 31573936
  • 113 + 31573823 = 31573936
  • 179 + 31573757 = 31573936
  • 239 + 31573697 = 31573936
  • 257 + 31573679 = 31573936
  • 293 + 31573643 = 31573936

Showing the first eight; more decompositions exist.
