Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527090, here are decompositions:

  • 13 + 31527077 = 31527090
  • 43 + 31527047 = 31527090
  • 73 + 31527017 = 31527090
  • 79 + 31527011 = 31527090
  • 137 + 31526953 = 31527090
  • 149 + 31526941 = 31527090
  • 151 + 31526939 = 31527090
  • 163 + 31526927 = 31527090

Showing the first eight; more decompositions exist.
