Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547046, here are decompositions:

  • 7 + 31547039 = 31547046
  • 43 + 31547003 = 31547046
  • 59 + 31546987 = 31547046
  • 109 + 31546937 = 31547046
  • 137 + 31546909 = 31547046
  • 199 + 31546847 = 31547046
  • 229 + 31546817 = 31547046
  • 233 + 31546813 = 31547046

Showing the first eight; more decompositions exist.
