Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492264, here are decompositions:

  • 3 + 31492261 = 31492264
  • 5 + 31492259 = 31492264
  • 101 + 31492163 = 31492264
  • 107 + 31492157 = 31492264
  • 173 + 31492091 = 31492264
  • 191 + 31492073 = 31492264
  • 197 + 31492067 = 31492264
  • 233 + 31492031 = 31492264

Showing the first eight; more decompositions exist.
