Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526808, here are decompositions:

  • 17 + 31526791 = 31526808
  • 31 + 31526777 = 31526808
  • 37 + 31526771 = 31526808
  • 59 + 31526749 = 31526808
  • 139 + 31526669 = 31526808
  • 191 + 31526617 = 31526808
  • 281 + 31526527 = 31526808
  • 311 + 31526497 = 31526808

Showing the first eight; more decompositions exist.
