Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548584, here are decompositions:

  • 7 + 31548577 = 31548584
  • 37 + 31548547 = 31548584
  • 157 + 31548427 = 31548584
  • 241 + 31548343 = 31548584
  • 271 + 31548313 = 31548584
  • 283 + 31548301 = 31548584
  • 577 + 31548007 = 31548584
  • 631 + 31547953 = 31548584

Showing the first eight; more decompositions exist.
