Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528312, here are decompositions:

  • 29 + 31528283 = 31528312
  • 71 + 31528241 = 31528312
  • 83 + 31528229 = 31528312
  • 191 + 31528121 = 31528312
  • 293 + 31528019 = 31528312
  • 311 + 31528001 = 31528312
  • 653 + 31527659 = 31528312
  • 743 + 31527569 = 31528312

Showing the first eight; more decompositions exist.
