Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519328, here are decompositions:

  • 7 + 31519321 = 31519328
  • 31 + 31519297 = 31519328
  • 229 + 31519099 = 31519328
  • 271 + 31519057 = 31519328
  • 367 + 31518961 = 31519328
  • 571 + 31518757 = 31519328
  • 727 + 31518601 = 31519328
  • 739 + 31518589 = 31519328

Showing the first eight; more decompositions exist.
