Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547048, here are decompositions:

  • 61 + 31546987 = 31547048
  • 67 + 31546981 = 31547048
  • 79 + 31546969 = 31547048
  • 139 + 31546909 = 31547048
  • 157 + 31546891 = 31547048
  • 241 + 31546807 = 31547048
  • 307 + 31546741 = 31547048
  • 331 + 31546717 = 31547048

Showing the first eight; more decompositions exist.
