Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548468, here are decompositions:

  • 37 + 31548431 = 31548468
  • 41 + 31548427 = 31548468
  • 67 + 31548401 = 31548468
  • 137 + 31548331 = 31548468
  • 167 + 31548301 = 31548468
  • 181 + 31548287 = 31548468
  • 199 + 31548269 = 31548468
  • 359 + 31548109 = 31548468

Showing the first eight; more decompositions exist.
