Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586012, here are decompositions:

  • 109 + 31585903 = 31586012
  • 163 + 31585849 = 31586012
  • 229 + 31585783 = 31586012
  • 349 + 31585663 = 31586012
  • 433 + 31585579 = 31586012
  • 463 + 31585549 = 31586012
  • 571 + 31585441 = 31586012
  • 613 + 31585399 = 31586012

Showing the first eight; more decompositions exist.
