Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514530, here are decompositions:

  • 17 + 31514513 = 31514530
  • 53 + 31514477 = 31514530
  • 101 + 31514429 = 31514530
  • 107 + 31514423 = 31514530
  • 233 + 31514297 = 31514530
  • 239 + 31514291 = 31514530
  • 263 + 31514267 = 31514530
  • 269 + 31514261 = 31514530

Showing the first eight; more decompositions exist.
