Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528864, here are decompositions:

  • 11 + 31528853 = 31528864
  • 23 + 31528841 = 31528864
  • 41 + 31528823 = 31528864
  • 53 + 31528811 = 31528864
  • 113 + 31528751 = 31528864
  • 167 + 31528697 = 31528864
  • 251 + 31528613 = 31528864
  • 317 + 31528547 = 31528864

Showing the first eight; more decompositions exist.
