Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548384, here are decompositions:

  • 41 + 31548343 = 31548384
  • 53 + 31548331 = 31548384
  • 61 + 31548323 = 31548384
  • 71 + 31548313 = 31548384
  • 83 + 31548301 = 31548384
  • 97 + 31548287 = 31548384
  • 103 + 31548281 = 31548384
  • 251 + 31548133 = 31548384

Showing the first eight; more decompositions exist.
