Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546984, here are decompositions:

  • 3 + 31546981 = 31546984
  • 47 + 31546937 = 31546984
  • 71 + 31546913 = 31546984
  • 137 + 31546847 = 31546984
  • 167 + 31546817 = 31546984
  • 263 + 31546721 = 31546984
  • 347 + 31546637 = 31546984
  • 383 + 31546601 = 31546984

Showing the first eight; more decompositions exist.
