Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550302, here are decompositions:

  • 89 + 31550213 = 31550302
  • 101 + 31550201 = 31550302
  • 149 + 31550153 = 31550302
  • 191 + 31550111 = 31550302
  • 239 + 31550063 = 31550302
  • 281 + 31550021 = 31550302
  • 383 + 31549919 = 31550302
  • 503 + 31549799 = 31550302

Showing the first eight; more decompositions exist.
