Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546340, here are decompositions:

  • 3 + 31546337 = 31546340
  • 37 + 31546303 = 31546340
  • 61 + 31546279 = 31546340
  • 73 + 31546267 = 31546340
  • 109 + 31546231 = 31546340
  • 181 + 31546159 = 31546340
  • 211 + 31546129 = 31546340
  • 229 + 31546111 = 31546340

Showing the first eight; more decompositions exist.
