Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527078, here are decompositions:

  • 31 + 31527047 = 31527078
  • 61 + 31527017 = 31527078
  • 67 + 31527011 = 31527078
  • 137 + 31526941 = 31527078
  • 139 + 31526939 = 31527078
  • 151 + 31526927 = 31527078
  • 157 + 31526921 = 31527078
  • 179 + 31526899 = 31527078

Showing the first eight; more decompositions exist.
