Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554184, here are decompositions:

  • 3 + 31554181 = 31554184
  • 5 + 31554179 = 31554184
  • 23 + 31554161 = 31554184
  • 41 + 31554143 = 31554184
  • 107 + 31554077 = 31554184
  • 173 + 31554011 = 31554184
  • 191 + 31553993 = 31554184
  • 197 + 31553987 = 31554184

Showing the first eight; more decompositions exist.
