Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546760, here are decompositions:

  • 19 + 31546741 = 31546760
  • 43 + 31546717 = 31546760
  • 97 + 31546663 = 31546760
  • 103 + 31546657 = 31546760
  • 127 + 31546633 = 31546760
  • 139 + 31546621 = 31546760
  • 163 + 31546597 = 31546760
  • 277 + 31546483 = 31546760

Showing the first eight; more decompositions exist.
