Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547088, here are decompositions:

  • 11 + 31547077 = 31547088
  • 101 + 31546987 = 31547088
  • 107 + 31546981 = 31547088
  • 151 + 31546937 = 31547088
  • 179 + 31546909 = 31547088
  • 197 + 31546891 = 31547088
  • 227 + 31546861 = 31547088
  • 241 + 31546847 = 31547088

Showing the first eight; more decompositions exist.
