Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527012, here are decompositions:

  • 59 + 31526953 = 31527012
  • 71 + 31526941 = 31527012
  • 73 + 31526939 = 31527012
  • 109 + 31526903 = 31527012
  • 113 + 31526899 = 31527012
  • 131 + 31526881 = 31527012
  • 149 + 31526863 = 31527012
  • 193 + 31526819 = 31527012

Showing the first eight; more decompositions exist.
