Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504896, here are decompositions:

  • 13 + 31504883 = 31504896
  • 23 + 31504873 = 31504896
  • 97 + 31504799 = 31504896
  • 113 + 31504783 = 31504896
  • 149 + 31504747 = 31504896
  • 193 + 31504703 = 31504896
  • 229 + 31504667 = 31504896
  • 277 + 31504619 = 31504896

Showing the first eight; more decompositions exist.
