Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566110, here are decompositions:

  • 31 + 31566079 = 31566110
  • 67 + 31566043 = 31566110
  • 97 + 31566013 = 31566110
  • 109 + 31566001 = 31566110
  • 139 + 31565971 = 31566110
  • 157 + 31565953 = 31566110
  • 181 + 31565929 = 31566110
  • 193 + 31565917 = 31566110

Showing the first eight; more decompositions exist.
