Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514388, here are decompositions:

  • 79 + 31514309 = 31514388
  • 97 + 31514291 = 31514388
  • 127 + 31514261 = 31514388
  • 149 + 31514239 = 31514388
  • 167 + 31514221 = 31514388
  • 197 + 31514191 = 31514388
  • 229 + 31514159 = 31514388
  • 239 + 31514149 = 31514388

Showing the first eight; more decompositions exist.
