Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607344, here are decompositions:

  • 3 + 31607341 = 31607344
  • 17 + 31607327 = 31607344
  • 47 + 31607297 = 31607344
  • 53 + 31607291 = 31607344
  • 107 + 31607237 = 31607344
  • 137 + 31607207 = 31607344
  • 191 + 31607153 = 31607344
  • 257 + 31607087 = 31607344

Showing the first eight; more decompositions exist.
