Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547964, here are decompositions:

  • 5 + 31547959 = 31547964
  • 11 + 31547953 = 31547964
  • 31 + 31547933 = 31547964
  • 43 + 31547921 = 31547964
  • 47 + 31547917 = 31547964
  • 103 + 31547861 = 31547964
  • 113 + 31547851 = 31547964
  • 127 + 31547837 = 31547964

Showing the first eight; more decompositions exist.
