Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456, here are decompositions:

  • 59 + 31397 = 31456
  • 137 + 31319 = 31456
  • 149 + 31307 = 31456
  • 179 + 31277 = 31456
  • 197 + 31259 = 31456
  • 233 + 31223 = 31456
  • 263 + 31193 = 31456
  • 317 + 31139 = 31456

Showing the first eight; more decompositions exist.
