Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528908, here are decompositions:

  • 67 + 31528841 = 31528908
  • 97 + 31528811 = 31528908
  • 101 + 31528807 = 31528908
  • 107 + 31528801 = 31528908
  • 157 + 31528751 = 31528908
  • 167 + 31528741 = 31528908
  • 179 + 31528729 = 31528908
  • 211 + 31528697 = 31528908

Showing the first eight; more decompositions exist.
