Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545326, here are decompositions:

  • 3 + 31545323 = 31545326
  • 229 + 31545097 = 31545326
  • 277 + 31545049 = 31545326
  • 499 + 31544827 = 31545326
  • 577 + 31544749 = 31545326
  • 607 + 31544719 = 31545326
  • 613 + 31544713 = 31545326
  • 739 + 31544587 = 31545326

Showing the first eight; more decompositions exist.
