Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545684, here are decompositions:

  • 17 + 31545667 = 31545684
  • 43 + 31545641 = 31545684
  • 61 + 31545623 = 31545684
  • 73 + 31545611 = 31545684
  • 197 + 31545487 = 31545684
  • 277 + 31545407 = 31545684
  • 283 + 31545401 = 31545684
  • 293 + 31545391 = 31545684

Showing the first eight; more decompositions exist.
