Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545192, here are decompositions:

  • 11 + 31545181 = 31545192
  • 73 + 31545119 = 31545192
  • 101 + 31545091 = 31545192
  • 109 + 31545083 = 31545192
  • 131 + 31545061 = 31545192
  • 191 + 31545001 = 31545192
  • 223 + 31544969 = 31545192
  • 229 + 31544963 = 31545192

Showing the first eight; more decompositions exist.
