Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528896, here are decompositions:

  • 43 + 31528853 = 31528896
  • 53 + 31528843 = 31528896
  • 73 + 31528823 = 31528896
  • 83 + 31528813 = 31528896
  • 89 + 31528807 = 31528896
  • 167 + 31528729 = 31528896
  • 173 + 31528723 = 31528896
  • 199 + 31528697 = 31528896

Showing the first eight; more decompositions exist.
