Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546380, here are decompositions:

  • 11 + 31546369 = 31546380
  • 29 + 31546351 = 31546380
  • 31 + 31546349 = 31546380
  • 43 + 31546337 = 31546380
  • 79 + 31546301 = 31546380
  • 97 + 31546283 = 31546380
  • 101 + 31546279 = 31546380
  • 113 + 31546267 = 31546380

Showing the first eight; more decompositions exist.
