Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514312, here are decompositions:

  • 3 + 31514309 = 31514312
  • 73 + 31514239 = 31514312
  • 163 + 31514149 = 31514312
  • 199 + 31514113 = 31514312
  • 211 + 31514101 = 31514312
  • 421 + 31513891 = 31514312
  • 433 + 31513879 = 31514312
  • 439 + 31513873 = 31514312

Showing the first eight; more decompositions exist.
