Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545464, here are decompositions:

  • 73 + 31545391 = 31545464
  • 283 + 31545181 = 31545464
  • 367 + 31545097 = 31545464
  • 373 + 31545091 = 31545464
  • 397 + 31545067 = 31545464
  • 463 + 31545001 = 31545464
  • 523 + 31544941 = 31545464
  • 541 + 31544923 = 31545464

Showing the first eight; more decompositions exist.
