Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550722, here are decompositions:

  • 11 + 31550711 = 31550722
  • 23 + 31550699 = 31550722
  • 41 + 31550681 = 31550722
  • 149 + 31550573 = 31550722
  • 179 + 31550543 = 31550722
  • 191 + 31550531 = 31550722
  • 251 + 31550471 = 31550722
  • 263 + 31550459 = 31550722

Showing the first eight; more decompositions exist.
