Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548494, here are decompositions:

  • 67 + 31548427 = 31548494
  • 151 + 31548343 = 31548494
  • 163 + 31548331 = 31548494
  • 181 + 31548313 = 31548494
  • 193 + 31548301 = 31548494
  • 463 + 31548031 = 31548494
  • 487 + 31548007 = 31548494
  • 541 + 31547953 = 31548494

Showing the first eight; more decompositions exist.
