Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31216, here are decompositions:

  • 23 + 31193 = 31216
  • 137 + 31079 = 31216
  • 197 + 31019 = 31216
  • 233 + 30983 = 31216
  • 239 + 30977 = 31216
  • 347 + 30869 = 31216
  • 443 + 30773 = 31216
  • 503 + 30713 = 31216

Showing the first eight; more decompositions exist.
