Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528884, here are decompositions:

  • 31 + 31528853 = 31528884
  • 41 + 31528843 = 31528884
  • 43 + 31528841 = 31528884
  • 53 + 31528831 = 31528884
  • 61 + 31528823 = 31528884
  • 71 + 31528813 = 31528884
  • 73 + 31528811 = 31528884
  • 83 + 31528801 = 31528884

Showing the first eight; more decompositions exist.
