Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545296, here are decompositions:

  • 199 + 31545097 = 31545296
  • 229 + 31545067 = 31545296
  • 373 + 31544923 = 31545296
  • 397 + 31544899 = 31545296
  • 439 + 31544857 = 31545296
  • 547 + 31544749 = 31545296
  • 577 + 31544719 = 31545296
  • 709 + 31544587 = 31545296

Showing the first eight; more decompositions exist.
