Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499302, here are decompositions:

  • 5 + 31499297 = 31499302
  • 11 + 31499291 = 31499302
  • 71 + 31499231 = 31499302
  • 113 + 31499189 = 31499302
  • 239 + 31499063 = 31499302
  • 269 + 31499033 = 31499302
  • 281 + 31499021 = 31499302
  • 311 + 31498991 = 31499302

Showing the first eight; more decompositions exist.
