Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546166, here are decompositions:

  • 7 + 31546159 = 31546166
  • 13 + 31546153 = 31546166
  • 37 + 31546129 = 31546166
  • 97 + 31546069 = 31546166
  • 103 + 31546063 = 31546166
  • 307 + 31545859 = 31546166
  • 499 + 31545667 = 31546166
  • 727 + 31545439 = 31546166

Showing the first eight; more decompositions exist.
