Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576306, here are decompositions:

  • 17 + 31576289 = 31576306
  • 23 + 31576283 = 31576306
  • 53 + 31576253 = 31576306
  • 107 + 31576199 = 31576306
  • 137 + 31576169 = 31576306
  • 239 + 31576067 = 31576306
  • 257 + 31576049 = 31576306
  • 269 + 31576037 = 31576306

Showing the first eight; more decompositions exist.
