Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546900, here are decompositions:

  • 53 + 31546847 = 31546900
  • 83 + 31546817 = 31546900
  • 101 + 31546799 = 31546900
  • 179 + 31546721 = 31546900
  • 191 + 31546709 = 31546900
  • 239 + 31546661 = 31546900
  • 263 + 31546637 = 31546900
  • 317 + 31546583 = 31546900

Showing the first eight; more decompositions exist.
