Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548498, here are decompositions:

  • 31 + 31548467 = 31548498
  • 67 + 31548431 = 31548498
  • 71 + 31548427 = 31548498
  • 97 + 31548401 = 31548498
  • 167 + 31548331 = 31548498
  • 197 + 31548301 = 31548498
  • 199 + 31548299 = 31548498
  • 211 + 31548287 = 31548498

Showing the first eight; more decompositions exist.
