Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548480, here are decompositions:

  • 13 + 31548467 = 31548480
  • 37 + 31548443 = 31548480
  • 53 + 31548427 = 31548480
  • 79 + 31548401 = 31548480
  • 137 + 31548343 = 31548480
  • 149 + 31548331 = 31548480
  • 157 + 31548323 = 31548480
  • 167 + 31548313 = 31548480

Showing the first eight; more decompositions exist.
