Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547004, here are decompositions:

  • 7 + 31546997 = 31547004
  • 17 + 31546987 = 31547004
  • 23 + 31546981 = 31547004
  • 67 + 31546937 = 31547004
  • 113 + 31546891 = 31547004
  • 157 + 31546847 = 31547004
  • 173 + 31546831 = 31547004
  • 191 + 31546813 = 31547004

Showing the first eight; more decompositions exist.
