Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546768, here are decompositions:

  • 47 + 31546721 = 31546768
  • 59 + 31546709 = 31546768
  • 107 + 31546661 = 31546768
  • 131 + 31546637 = 31546768
  • 167 + 31546601 = 31546768
  • 311 + 31546457 = 31546768
  • 317 + 31546451 = 31546768
  • 347 + 31546421 = 31546768

Showing the first eight; more decompositions exist.
