Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548550, here are decompositions:

  • 3 + 31548547 = 31548550
  • 17 + 31548533 = 31548550
  • 23 + 31548527 = 31548550
  • 29 + 31548521 = 31548550
  • 83 + 31548467 = 31548550
  • 107 + 31548443 = 31548550
  • 149 + 31548401 = 31548550
  • 227 + 31548323 = 31548550

Showing the first eight; more decompositions exist.
